Gregor Mendel's Theories of Genetic Inheritance

Gregor Mendel played a huge role in the underlying principles of genetic inheritance. He grew up in a Augustinian brotherhood where he learned agricultural training with basic education. He then went on to the Olmutz
Philisophical Institute and then entered the Augustinian Monestary in 1843.
After 3 years of theological studies, Mendel went to the University of Vienna where he was influenced by 2 professors, the physicist Doppler and a botanist named Unger. Here he learned to study science through experimentation and aroused his interest in the causes of variation in plants. Then in 1857, Mendel began breeding garden peas in the abbey garen to study inheritance which lead to his law of Segregation and independent assortment.
Mendel's Law of Segregation stated that the members of a paror of homologous chromosomes segregate during meiosis and are distributed to different gametes. This hypothesis can be divided into four main ideas. The first idea is that alternative versions of genes account for variations in inherited characters. Different alleles will create different variations in inherited characters. The sescond idea is that for each character, an organism inherits two genes, one form each parent. So this means that a homolohous loci may have matching alleles, as in the true-breeding plants of Mendel's P generation(parental). If the alleles differ, then there will be F hybrids. The third idea states that if the two alleles differ, the receessive allele will have no affect on the organism's appearance. So a F hybrid plant that has purple flowers, the dominant allele will be the purple-color allele and the recessive allele would be the white-color allele.

  • Brassica Rapa Hypothesis

    651 Words  | 2 Pages

    The purpose of our experiment was to test whether or not the Wisconsin Fast Plants, or Brassica rapa, followed the Mendelian genetics and its law of inheritance. First, after we crossed the heterozygous F1 generation, we created an F2 generation which we used to analyze. After analyzing our results, we conducted a chi-square test for for both the F1 and F2 generations to test their “goodness of fit”. For the F1 generation we calculated an x2 value of 6.97, which was greater than the value on the chi-square table at a p-value of 0.05 and 1 degree of freedom (6.97 > 3.84). This meant that we had to reject our hypothesis that stated there would be no difference between the observed and expected values. This showed us that the F1

    Bullying is a serious issue that can occur to various people of different age and background. It is considered a serious problem because of the long lasting health problems that comes with it. The many effects of bullying such as, depression and alcoholism can cause changes in our genes which can possibly be passed on to the future generations. In Sharon Moalem’s essay “Changing Our Genes: How Trauma, Bullying, and Royal Jelly Alter Our Genetic Destiny” he discussed about the effects of bullying on the victims and how it causes gene changes. It is important to know how to prevent bullying as the effects can influence a person mentally and genetically which can be passed on to future generations later on.

  • Genetic Dilemmas Dena Davis Summary

    744 Words  | 2 Pages

    Dena Davis in the 5th chapter of “Genetic Dilemmas: Reproductive Technology, Parental Choices, and Children’s Futures” explores the global attitudes, policies, and morality towards determination of sex. She begins with presenting empirical evidence of some preferences held in countries such as India or China where there is a clear desire for male children. This inclination is so deeply held that mothers can be socially and physically harmed when, by pure biological chance, they fail to produce a male child. Davis and others allow sex selection in these cases, purely in the interest of harm reduction of mothers and their daughters born into such a situation. This example is contrasted with so-called “western” societies, where the preference

    The double murder case of O.J. Simpson is one that will live on forever and one that will never be forgotten. On June 12, 1994 Nicole Brown Simpson and Ronald Goldman were found dead at Nicole’s home in Los Angeles. According to Doug Linder, it was “most likely a single male that came through the back entrance of Nicole Brown Simpson’s condominium” (Linder). Since they did not have any other suspects they went right to Orenthal James Simpson who was Nicole Simpson’s ex-husband. Law enforcement had seen him as suspicious and they had charged him with both of the murders. The case had gone to trial and it was the prosecutor’s job to prove beyond a reasonable doubt that Simpson was guilty and that he had done the crime. Simpson had what was called

  • Examining the Crosses Between Drosophila Fruit Flies

    613 Words  | 2 Pages

    The major topic of this experiment was to examine two different crosses between Drosophila fruit flies and to determine how many flies of each phenotype were produced. Phenotype refers to an individual’s appearance, where as genotype refers to an individual’s genes. The basic law of genetics that was examined in this lab was formulated by a man often times called the “father of genetics,” Gregor Mendel. He determined that individuals have two alternate forms of a gene, referred to as two alleles. An individual can me homozygous dominant (two dominant alleles, AA), homozygous recessive, (two recessive alleles, aa), or heterozygous (one dominant and one recessive allele, Aa). There were tow particular crosses that took place in this experiment. The first cross-performed was Ebony Bodies versus Vestigle Wings, where Long wings are dominant over short wings and normal bodies are dominant over black bodies. The other cross that was performed was White versus Wild where red eyes in fruit flies are dominant over white eyes.

  • The Deaf Community and Deaf Culture

    1208 Words  | 3 Pages

    In the United States today, approximately 4500 children are born deaf each year, and numerous other individuals suffer injuries or illnesses that can cause partial or total loss of hearing, making them the largest “disability” segment in the country. Although, those in the medical field focus solely on the medical aspects of hearing loss and deafness, members of the deaf community find this unwarranted focus limiting and restrictive; because of its failure to adequately delineate the sociological aspects and implications of the deaf and their culture. Present day members of deaf culture reject classifications such as “deaf mute” or “deaf and dumb”, as marginalizing them because of their allusions to a presumed disability. (Edwards, 2012, p. 26-30)

  • Deafness In The Deaf Community

    1642 Words  | 4 Pages

    Deafness itself has historically been viewed as a physical impairment, similar to blindness, and both cognitive and motor impairments. Though today, deafness is considered a trait, not a disability. The debilitating effects of deafness can be helped through hearing aids, cochlear implants, assistive listening devices, and through the ability of speech (and visually reading others lips). Any traits that group members share can be perceived as positive by people in that group. So if deafness is seen as a disability, then people who are deaf carry the stigma of “lacking” a typical human characteristic. Although people in the Deaf Community say they are bound together by deafness, they also say that being deaf is a distinctive perspective on the world.

    Mendel’s law of segregation states that offspring receive only one of two alleles of a gene from the parent (Brooker et al. 2014). This means that utilizing a monohybrid cross where each parent has both a dominant allele of a gene and a recessive allele, that by producing offspring of these plants, a predictable outcome of trait inheritance should be observed (Brooker et al. 2014). This experiment investigated the inheritance of anthocyanin in Brassica rapa.

  • Apterous Experiment

    1326 Words  | 3 Pages

    In this experiment, Mendelain Models are observed. The purpose of the experiment is to understand how traits are passed from one generation to the other as well as understanding the difference between sex linked and autosomal genes. One particular trait that is observed in this experiment is when a fly is lacking wings, also known as an apterous mutation. In this experiment, we will determine whether this mutation is carried on an autosomal chromosome or on a sex chromosome. The data for this experiment will be determined statistically with the aid of a chi-square. If the trait is autosomal, then it will be able to be passed to the next generation on an autosomal chromosome, meaning that there should be an equal amount of male and

  • Genetic Determinism

    On Christmas Day in the year 2001, I gave birth to a healthy baby boy. When I looked into the brand-new face of my son I saw a beautiful mystery. I wondered what kind of man my boy would grow to be and what his life would be like. There are those in the scientific community who would argue that my son's path was already determined at the moment of his birth, that his fate could be deciphered from his genetic make-up. As a nurturing mother I know better. At two years old my son has developed a more diverse vocabulary than many children twice or even three times his age. He recognizes many written words and reads them aloud. He is able to spell his name. He can distinguish a square from a rectangle and an octagon from a hexagon. Was he born with this knowledge? The answer is no. My son, as genetically gifted as he may be, could have been born into an environment in which his inborn potential was never developed. The knowledge he now possesses can be directly traced to the teaching environment in which he has grown. Human beings are a product of both their biology and their environment.

  • Discrimination Against the Deaf Culture

    2335 Words  | 5 Pages

    The deaf community does not see their hearing impairment as a disability but as a culture which includes a history of discrimination, racial prejudice, and segregation. According to an online transcript,“Through Deaf Eyes” (Weta and Florentine films/Hott productions Inc., 2007) there are thirty-five million Americans that are hard of hearing. Out of the thirty-five million an estimated 300,000 people are completely deaf. There are ninety percent of deaf people who have hearing parents (Halpern, C., 1996). Also, most deaf parents have hearing children. With this being the exemplification, deaf people communicate on a more intimate and significant level with hearing people all their lives. “Deaf people can be found in every ethnic group, every region, and every economic class” (Weta and Florentine films/Hott productions Inc., 2007). The deaf culture and hard of hearing have plenty of arguments and divisions with living in a hearing world without sound however, that absence will be a starting point of an identity within their culture as well as the hearing culture (Weta and Florentine films/Hott productions Inc., 2007).

    Many of Darwin’s contemporaries in the nineteenth century disagreed with Darwin’s theory, at that time most people were religious and saw concepts, theories in one lens refusing to question God’s authority and what He had created. So according to their limited mindset the “nineteenth century critics of Darwin thought that he had misinterpreted the Galapagos finch data.” they said God had created the 13 different species as they are and that no evolution in beak shape has ever occurred.” O’Neil, D (2013:05) Therefore the Darwin’s theory was challenged at the time based on religious views.
