Title: Population Genetics of Drosophila Melanogaster Introduction: In population genetics, the Hardy-Weinberg Principle is the relationship between the frequency of alleles and the genotype of the population. The population is said to be in genetic equilibrium, when Hardy-Weinberg conditions are met. The five Hardy-Weinberg conditions are: no mutations, no migration can occur in the population, population size must be large, and survival and reproduction success of population members must be random and independent of their genotypes. In this experiment, we will be using fruit flies (Drosophila Melanogastor) to illustrate the Hardy-Weinburg Principle. As long as Hardy- Weinberg conditions are met, we will be able to use p+q=1 to determine the allele frequencies of the dominant, red (p) allele and the recessive sepia (q) allele. Additionally, we will illustrate the process of evolution by selecting against flies that posses the sepia (brown eyed) eye color and in favor of the wild type
