    Gamble My mind was a crystal vase that contained only one desire, which was to win. I slumped back into my red leather chair, as the Slots machine again stole my money, it was my sixth loss in a row. The big flashing red words of “LOSS” on the digital screen and the loud voices of joy fed on my insecurities. I was sitting here bleary-eyed and unshaven in front of this wealthy machine, but I was only adding to its wealth, as I slowly munched through the family’s life savings. I just spent 2 hours…

    Ebony Lab Report

    Discussion: My first hypothesis that the sepia eye and ebony body experimental cross would result in a 9:3:3:1 ratio, and that the traits would be autosomal, unlinked recessive, was found to be false. I chose to reject my hypothesis because my calculated test statistic, 587.5, was larger than the critical value, 7.815. The traits, ebony and sepia, are linked, seeing that they fit in 2:1:1 linkage ratio and that the recombinant number is smaller (Table 1.1). They are autosomal; the amount of…

    Evolving Genetic Ideas

    • 5 Pages

    Evolving our Genetic Ideas Evolution was a recognized theory long before heredity was properly understood, however, Darwin has allowed us to understand human evolution to a far greater extent than he would have ever imagined. Genetics can be expressed in many different ways. The more often a specific phenotype is observed within the population may relate to how favourable that phenotype is for survival. This is because of relative frequency and lethality. Relative frequency is the number of…

    • 2 Pages

    Introduction Fruit fly Drosophila melanogaster that is used as a model to study genetics for more than a hundred years. Thomas Hunt Morgan, in the early 1900’s, used the heritable traits of a common species of fruit fly to develop our understanding of genetics. Morgan was the first to show through experiments that genes were located on chromosomes. He also found that certain fruit fly traits like eye color are found on the same chromosomes that also determine their sex. Fruit flies have several…

    • 5 Pages

    I would like to be genotyped to see if I am a carrier for certain alleles for Transcription Factor 7-Like 2 (TF7L2) gene and if my family is genetically susceptible to the diseases. In other words, I want to know which SNP and what genotype I hold. The reason behind my decision is that I know that T2D is caused by environment and genetics. Getting tested will help me take further actions if my results show that I have predisposition. Many factors contribute to type 2 diabetes,…

    meant to look and find gene linkages and determine the crosses of the tan x wild type (black), gray x wild type (black), and tan x gray spores of the Sordaria fimicola. To accomplish the crossing, the plates filled with auger had to be set up with each individual kind of spore. Three plates with two different spore colors of sordaria in each. One plate was black and tan, black and gray, and gray and tan. For gene to centromere distance the standard deviation was 5.6 (tan x wild) and 4.8 (wild x…
