Population Genetics Problems 1. In a population that is in Hardy-Weinberg equilibrium, the frequency of the allele “a” is 0.3. What is the percentage of the population that is homozygous for this allele? 2. In the foregoing population, what is the percentage of the population that is heterozygous for this locus? 3. In a population with two alleles, A and a, the frequency of “a” is 0.6. What would be the frequency of heterozygotes in the population if it is in H-W equilibrium? 4. You sample a population of butterflies and find that 42% are heterozygotes at a given locus. What would be the frequency of the recessive allele in this population? 5. A large population of lab animals has been allowed to breed randomly for a number of generations. After several generations, 64% of the animals display a recessive trait, the same percentage as at the beginning of the breeding program. The rest of the animals show the dominant phenotype, with heterozygotes indistinguishable from homozygous
