Genetics of Sickle Cell Anemia Objectives • To observe how a disease can act as a selective force • To describe changes in allele frequencies in a population as a result of a selective force Hypothesis The starting ratio of HbA to HbS is 3:1; in a typical population‚ the Homozygous Dominant Gene would become the standard‚ but because carrying the Heterozygous version of the allele has an advantage to fighting Malaria it will become the dominant Allele for the population. The HbA/HbS gene will

Genetics & Drosophila Melanogaster Lab Report Background: For two months‚ you will breed Drosphila melanogaster (fruit flies) and set up genetic crosses in order to determine the pattern of inheritance of certain mutant traits. The traits for which we will examine the pattern of inheritance are apterous (wingless)‚ vestigial (crippled wings) or white eyes. These are all mutant strains. The normal condition (winged and red eyes) is referred to as the wild type strain. Objective: The intial

PROBABILITY and MENDELIAN GENETICS LAB Hypothesis: If we toss the coin(s) for many times‚ then we will have more chances to reach the prediction that we expect based on the principle of probability. Results: As for part 1: probability of the occurrence of a single event‚ the deviation of heads and tails of 20 tosses is zero‚ which means that the possibility of heads and tails is ten to ten‚ which means equally chances. The deviation of heads and tails of 30 tosses is 4‚ which means that the

Cassie Browne Anthony Lulgjuraj Fly Lab Report Friday 9:30am Mutation #620 X Mutation #644 1) The vial labeled Mutation #620 contained female flies that displayed a mutation in eye color. This mutation causes a change in eye pigment from wild type (bright red) to a dark‚ reddish brown. The males possessed mutation #644. It is a mutation in wing morphology that reduces wing size. A controlled cross was conducted between these two true-breeding mutant flies. Their progeny (F1) being heterozygous for
