To understand Mendel’s theory I think it is also important to understand Darwin’s theory. “Darwin’s theory of evolution is the widely held notion that all life is related and has descended from a common ancestor; the birds and the bananas, the fishes and the flower—all related” (All About Science, 2011). Darwin’s theory is what drew Mendel to study genetics. So where Darwin believed that everything was related in some way through evolution, Mendel’s theories differed proving that genetics is the hereditary factor that links and evolved life. Mendel attempted to track specific genes instead of specific phenotypes. Mendel’s experiment basically fathered genetics. He knew nothing about DNA yet he was still able to show how traits are inherited. He obviously proved that traits come from alleles and that traits do not just mix and is then lost forever because some traits can be recovered. Mendel used the garden pea experiment to help describe how traits are inherited. “He made the fortuitous choice to study the pea, which is an organism that can be easily manipulated in breeding experiments” (Axia College, 2011). The pea has a short generation time so Mendel was able to study multiple pea plants at once. Their phenotypes are very distinct which is ultimately better because the experiment was basically to study specific phenotypes by color, growth, etc. One major concluding principle Mendel hypothesized from his works was hereditary characteristics. For example, a mother and father of a child will pass on genetic characteristics to their child. Mendel’s theory is that many hereditary genes otherwise known as alleles are passed on to give a child similar characteristics of his or her parents. Another major principle of Mendel’s hypothesis is an offspring carries two alleles for every single gene (Axia College, 2011). The alleles can be identical or…...

Eye Color Inheritance

...Eye Color Inheritance Eye color is a physical trait that is determined by the pairing of genes from both parents. Eye color is a polygenic trait, which means there are multiple genes that interact to produce the color. It was previously thought that a single gene pair following dominant and recessive inheritance patterns was responsible for eye color, but it is now known to be much more complex than that, involving at least three gene pairs. Geneticists have focused on two of the three gene pairs to help clarify the inheritance of eye color: EYCL1, called the gey gene, and EYCL3, called the bey2 gene. There are several genes which influence the color of a person's eyes. As a general rule brown eyed genes are often dominant and blue eyed genes tend to be recessive. These factors of genetic dominance are added to the complex genetic equation that our bodies use to determine our eye color. A green allele is dominant over a blue allele, and a brown allele is dominant over both green and blue alleles. For the bey 2 gene if a person has a brown allele then they will have brown eyes. In the gey gene the green allele is dominant over the blue allele, but it is still recessive next to a brown allele. All four alleles must be blue to produce a blue eyed person. Another way of predicting the color of a child's eyes is to use the parent's eye color genes. In my family, my mother as well as my father has blue eyes. I am a one of three children they had. To be more exact, I am a triplet...

Widows and Widowhood Inheritance

...refers to depriving someone of acquired or inherited movable or immovable possessions that rightfully and legally belong to that person (The South African Concise Oxford Dic tionary; Kuenyehia 2003). This study uses stripping and grabbing interchangeably as refer ring to the same act. Basing their studies in Ikot Idem in Nigeria, Okunmadewa, Aina, Ayoola, Mamman, Nweze, Odebiyi, Shedu and Zacha (2002:106) maintain: [W]omen’s wellbeing often deteriorates quickly after the loss of their husbands, when they suffer threats of both their physical security and property. A widow often loses her husband’s property to the in-laws in accordance with family traditional rules. This study proposes to explore the widows’ experiences of property inheritance in the Binga District, in the North West of Zimbabwe. Economically, people in Binga practice subsistence farming, animal rearing, and gathering natural fruits. People also enjoy the liberty of fishing in the Zambezi River and this is why they are called Basilwizi, that is people of the great river. The educational level in the district is low, more so among women in all population age groups. Socio-culturally, the Tonga people adhere strongly to 1 their culture and do not easily accept unexplained outside influence towards change. Polygamy and levirate marriage are strong cultural practices in the district despite HIV and AIDS. Customary marriage is very common among the people and women are generally a subordinate......

Mendel Paper Company

...Mendel Paper Company Intro In the case of Mendel Paper Company which produces four basic paper products lines at one of its plants: computer paper, napkins, place mats, and poster board. Although the plant superintendent, Marlene Herbert is pleases with increased sales he is also concerned about the costs. The superintendent is concerned with the high fixed cost of production, the increases in fixed overhead and even variable overhead. He feels that the production of place mat should be discontinued. His reason for the discontinuation is that the special printing is driving up the variable overhead to the point where the company may not find it profitable to continue with the line. After reviewing the future predictions of the company I will answer the superintendent concerns by using both new and previous calculations to support my recommendation. Question one 1.

Inheritance Law

...Inheritance Law in Belgium and Switzerland Marieke Martens We live, we work and we die. People basically work to make money and spend it but also save it. After somebody has died what will happen to the money and the possessions? Firstly the division of the money and possessions takes place, according to the will. But what if there is now will? If there is a will or not, the possessions and money will not be inherited for free. The inheritance law is a collection of articles, which explains what happens to and with the inheritance of the person who died when there is no will and when there is a will. In this paper two countries will be compared based on their inheritance law. The first country is Belgium, which is part of the EU and has no specific advantages if it comes to being a tax paradise. The other country, which will be used in this research, is Switzerland, which is not part of the EU and is very famous for being a tax paradise. Both countries do have one thing in common: they are both West-European countries. Because Switzerland is a tax paradise it can be assumed that the inheritance law in Switzerland is more favourable than in the Belgium. This statement basically states that in Switzerland you have to pay less inheritance tax, there are better condition if it comes to making wills or not, than in Belgium, which results in a higher inheritance than in Belgium. These are the fields of Inheritance law that will be covered in the paper in order to answer......

Gregor Johann Mendel

...Mendel Leben: Name: Gregor Johann Mendel geboren: 20. Juli 1822, gestorben 6. Januar 1884 Beruf: Katholischer Priester wird oft als „Vater der Genetik“ bezeichnet Kloster: Augustiner-Abtei St. Thomas in Alt Brünn 1856: Beginn systematischer Kreuzungsexperimente Vorgehensweise: Mendel kreuzte Pflanzen untereinander, um die Vererbung von Merkmalen zu erforschen. Er wählte zunächst Erbsenpflanzen, da sie mehrere konstante und unterschiedliche Merkmale aufweisen und der Blütenbau Fremdbestäubung verhindert, was die künstliche Befruchtung jedoch erschwert. Er befruchtete sie, indem er mit Pinzetten Pollen der einen Pflanze auf die Narbe der anderen auftrug und sie mithilfe von kleinen Papierbeuteln unter Verschluss hielt, sodass keine ungewollte Bestäubung durch z.B. Bienen oder Wind stattfinden konnte. Zusätzlich entfernte er vorzeitig die Staubgefäße. Er kreuzte zwei Jahre lang Erbsensorten, bis sie gleiche und konstante Nachkommen hatten. Diese waren die Grundlage für seine Kreuzungsversuche. Die Versuche waren genau geplant und wurden exakt protokolliert, sodass das Ergebnis statistisch abgesichert war. Dazu zählte er stets mehrere tausend Nachkommen aus. Mendel ging davon aus, dass die Eigenschaften in dem Organismus gemeinsam wirken, aber getrennt vorliegen. Dies widersprach der damaligen Auffassung, dass sich die Merkmale vermischen und nachher nicht mehr von einander getrennt werden können. Er kam so zu der Annahme, dass es......

Mendelian Inheritance

...Bio 405 Genetics Mendelian Inheritance This video is talking about the Mendelian genetics. This videos starts off by telling us the meaning of both genetics and heredity. Genetics can be used in many different subjects such as zoology, molecular biology, microbiology and topics dealing life as examples. It then goes on to discuss the father of genetics which is Gregor Mendel who was and Austrian monk that grew up with a family of religious beliefs. Throughout his life Gregor was interested in botany and mathematics. He is known as one of the first scientist applied mathematics to his science research. There was two viewpoints of heredity which where blending and particulate hypothesis. The blending hypothesis didn’t work when the father of evolution, Charles Darwin did not have enough evidence. The particulate hypothesis was then discovered by Gregor Mendel. This video also breaks down the meaning of genes and traits. You have different characteristics for genes and traits such a height, weight, and appearance. It then goes to tell us about the advantages Mendel had with us pea plants in his study. From the hybridization experiments, he induced two generalizations which later became known as Mendel's Principles of Heredity or Mendelian inheritance. The speaker of this video also proceeds to talk about alleles, which are known as variation of different genes. Most alleles are represented as the dominant trait. Mendel’s Principle of Dominance says that the......

The Unwanted Inheritance

...Dementia/Alzheimer’s – The Unwanted Inheritance Georgeanna L. Chapman COM/172 June 09, 2014 Janice Prewitt Dementia/Alzheimer’s – The Unwanted Inheritance It is time to start the day by getting up moving; standing there trying to remember the reason that they are perched there in the kitchen, but their brain isn’t operating correctly. Why can’t they remember what they walked in there for? It wasn’t like this yesterday, or was it is, but with the increasing symptoms of Alzheimer’s setting in, their world is changing, and there is nothing that they can do about it. Yesterday is a blur, today is starting out in a foggy cloud. Even though, environmental factors could contribute to the onset of Alzheimer’s, 25% of all people aged 55 have family history of the disease, 50% of them will inherit the gene mutation. More studies need to be done when it comes to Alzheimer’s; a disease that is increasing in numbers and it is time to put more emphasis on this. With the number of cases rising at a fast rate, women need to stand up and take a stand and demand that more studies be performed as they are more at risk to get Alzheimer’s than Cancer; nearly two-thirds of those with Alzheimer’s are women. “Alzheimer’s disease was first identified more than 100 years ago but still relatively little is known and understood about the aetiology, pathogenesis, treatment management and prevention of the disease. Diagnosis is difficult, particularly in the early stages, and effective......

Design Patterns

...Term paper On Design patterns Advanced topics in software engineering CSC 532 Submitted by:- Harpreet Singh Abstract:- Design patterns, a standard solution to problems in object oriented software engineering, are considered to be a well formed language to represent software design. Their benefits have been widely acknowledged by software professionals throughout the world. Design patterns can be classified according to multiple criteria the most common being the type of problem they solve. Till today many design patterns have been established and many more are being found as time passes. Patterns capture knowledge from various parts of software developing. Design patterns are helpful to the designers in a way that they represent the collective wisdom and experience of the community and their implementation leads to better quality software and also a novice designer does not find it difficult to understand the systems functionality. A very important advantage of design patterns is the fact that they speed up the development process by providing an almost ready-made solution that has been used earlier and proved to be efficient. Another advantage is that they allow for a generalized solution that does not depend on understanding a specific design problem from all its aspects, and thus ease reusing this solution. Apart from that they help the new developers to ignore traps and pitfalls which have earlier been learned by other developers by costly......

Dna Inheritance

...DNA Inheritance Joel Klingensmith BIO/101 Due Date: 10/12/2015 University of Phoenix Not all phenotypes can be seen. Blood types can only be observed by laboratory techniques. The ability to roll your tongue are phenotype variables. As humans, our shape, size, hair color, eye color, height and so on; are all about phenotype variables. I am able to recognize my family tree of all different phenotype variables, could be passed through genes or caused by environmental factors. Influencing body weight can be directed by genes or by diet, which is the environmental factor. Genotypes are the makeup of the cell where it leads next to the personal expressions, and characteristics; or better known as phenotypes. The blue eyes that are shown in my family tree, more occurring than the brown eyes, is a part of the characteristics. The blonde hair that my grandmother had is the phenotype, or my older brother being left handed is a phenotype. My grandfather’s baby blue eyes would be a trait I would pick out of the three generations. Choosing my grandfather’s blue eyes, I would make a hypothesis using the Punnett square. My grandfather’s parents would have each their own allele, either dominant or recessive. Each square in the Punnett square have a 25 percent chance. If my grandpa’s father had brown eyes, his alleles would be “Bb” for dominant and recessive, or two different alleles. If my grandfather’s mother had blue eyes, the genotypes would be “bb”. Taking those two......

Inheritance

...Inheritance between classes A key feature of C++ classes is inheritance. Inheritance allows to create classes which are derived from other classes, so that they automatically include some of its "parent's" members, plus its own. For example, we are going to suppose that we want to declare a series of classes that describe polygons like our CRectangle, or like CTriangle. They have certain common properties, such as both can be described by means of only two sides: height and base. This could be represented in the world of classes with a class CPolygon from which we would derive the two other ones: CRectangle and CTriangle. The class CPolygon would contain members that are common for both types of polygon. In our case: width and height. And CRectangle and CTriangle would be its derived classes, with specific features that are different from one type of polygon to the other. Classes that are derived from others inherit all the accessible members of the base class. That means that if a base class includes a member A and we derive it to another class with another member called B, the derived class will contain both members A and B. In order to derive a class from another, we use a colon (:) in the declaration of the derived class using the following format:  class derived_class_name: public base_class_name { /*...*/ }; Where derived_class_name is the name of the derived class and base_class_name is the name of the class on which it is based. The public access......

Inheritance

...Sex chromosomes produce very unique patterns of inheritance in living organisms. In humans, there is an X chromosome and a Y chromosome that determines the sex of the offspring. A male has an X and Y chromosome, whereas a female has two X chromosomes. The sex of an offspring is determined by whether the sperm cell that fertilizes the egg is made up of an X or a Y chromosome; ultimately the male is the determining factor of the sex of the offspring. Even though the Y chromosome determines if the offspring will be male, the X chromosome has genes that control certain human characters; these genes are called sex-linked genes because they are linked to a certain sex. There are approximately 1,098 sex-linked genes that code unusual inheritance patterns other than the female sex trait. Some of these sex-linked genes carry unusual inheritance such as color blindness, Duchenne muscular dystrophy and hemophilia. (O’Neil, 2012). In the case of the recessive mutation that causes hemophilia, a female has to be the carrier of the mutated allele, since she has the X chromosomes only. If the female carrier of the disease mates with a male who has hemophilia (XhY), there would be a one-quarter chance that they would produce a female offspring that has hemophilia (XhXh). Males though are more susceptible to inheriting the hemophilia trait if the mother is a carrier, because the dominant gene (XH) will prevent the disease. (Simon, 2015). Since males can only have an X and a Y chromosome, there...

Inheritance Activity

...Financial concepts are greatly important when determine which would be the best method to use for the firm or personal use. Some financial concepts are time value of money, risk and return, and interest rates. The activity of the assignment is to determine which options are best for the individual if the individual were given three alternatives of his or her inheritance; taking the $5,000 now, $1,000 for the next eight years, or taking a $12,000 at the end of the eight years. Assume that the individual can earn 11 percent interest annually. First, determine which what formulas will need to apply based on the way cash is being received. Perform the necessary calculations and determine which inheritance alternative would be best and why? Second, would he or she decision be different if he or she can earn interest at 12 percent? Without a proper calculation of the funds, decisions can be misconception. Receiving $5,000 cash now sound great and then invest for eight eights with 11 percent interest for the eight years. On the other hand, receiving $1,000 for the next eight years seems to be a little long and the amount is not that amazing but that $1,000 can be as large by the end of the eight years because the interest received increase each year—higher deposit at year two. For example, at year one, he or she invests $1,000 times that by the 11 percents interest rate will equal to $1,110 for the first year. For the second years, the interest will be calculate......

Gregor Mendel

...Mendel on Patterns of Inheritance Gregor Mendel, a monk, well read in natural sciences (Pruitt & Underwood, 2006, p. 64), wanted to answer the unanswered questions that stemmed from Darwin’s theory about heredity. He chose to study the pea plant to gain knowledge about how heredity works. Mendel’s success is contributed to the way he chose to conduct his experiments. Mendel decided to keep his control group small, unlike many of his colleagues, focusing on only seven traits. He kept excellent records of all of the results of the experiments and his choice to study the pea plant, “an organism that can be easily manipulated in breeding experiments” (Pruitt & Underwood, 2006, p. 64) proved to be a good move. Mendel also used “mathematical analysis” (Pruitt & Underwood, 2006, p. 64), an uncommon approach in his day, for showing results of the experiments. A few of Mendel’s discovered six major principles about heredity from his research. An example of one of his principles states that for every gene there are two factors or alleles, “the different forms a gene might take” (Pruitt & Underwood, 2006, p. 68). If an organism has two alike alleles for a specific trait the organism is considered homozygous for that trait; homo meaning the same. On the flip side, if an organism has two alleles that are different then the organism is considered heterozygous for that trait; hetero meaning different......
