  • Procter And Gamble Short Story

    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…

  • Essay On Color Blindness

    Color Blindness is defined as the inability or decreased ability to see color, or perceive color differences, under normal lighting conditions. Color blindness is also referred to as color vision deficiency. In the United States alone there are about three million cases noted per year for color blindness. This disorder seems to affect men more than it does women. It is estimated that around eight percent of males and a little less than one percent of females are diagnosed in the United…

  • Genotyped Essay

    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,…

  • Common Fruit Fly Experiment

    Drosophila Melanogaster, or better known as the common fruit fly, is found all over the world and referred to as the cosmopolitan species (Mitrick, 2010). This fruit fly has three main body parts, which include the head, the thorax, and the abdomen. On males, the bottom half of the abdomen is black, while on the female, each segment of the abdomen is striped black. Drosophila have four main stages to their life cycle. These include: egg, larva, pupa and adult. The eggs small and translucent eggs…

  • The Mendelian Genetic Experiment

    experiments on human is against the law of human right. Drosophila melanogaster (fruit flies) is one of the model organism that can be used for various applications. In this experiment, the fruit flies were used to observe the basic genetic mechanism, leading to understanding the mode of inheritances of other organisms since they all share similar genetic approach. Background Mendelian genetic is considered to the classic for genetic. There are three Mendel’s laws of genetics: the law of…

  • Unlinked Gene Hypothesis

    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…

  • Anorexia Nervos A Case Study

    There is another point to consider in genetics and anorexia. It is that maybe genetics and environment together can cause the onset of anorexia. There are two ways this can happen. One is gene-environment interaction, which basically means that if a person has a certain gene and is placed in the right environment, then that gene could be activated and could potentially cause anorexia. The other way is epigenetic effects. This is when the environment changes gene expression and can alter the…

  • Deoxyribonucleic Acid Vs Dna Research Paper

    Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) make up the nucleic acid in cells and is responsible for the differences in many of our traits. DNA is the substance in which our genetic material is carried on from one generation to the next. Nucleotides join together through phosphodiester linkages between the 5 ' and 3 ' carbon atoms to form nucleic acids. “Nucleotides are composed of a five-membered sugar group with a purine or pyrimidine nitrogen base group attached to its 1 ' carbon…

  • Linkage Analysis And Synthesis Essay

    For many decades, linkage analysis has been well-established and shown to be an effective tool for studying the complex quantitative traits. Despite of its great successes, this approach has great weakness because it only captures limited allelic diversity existing in two parental lines and also limited in low genomic resolution (Borevitz and Nordborg 2003). To address this issue, GWAS utilizing diverse germplasm collections and recombination events that have been accumulated during the…
