At a biallelic locus, suppose that genotypes A1A1, A1A2, and A2A2 have relative fitnesses 1, 1.02, and 1.03 and that the frequency of A1 is p = 0.1. (a) What is the population’s mean relative fitness? (b) What are the “marginal” or allele-specific relative fitnesses of A1 and A2? (c) What is the expected frequency of A1 in the following generation?

Scientists have identified three genotypes (A1A1, A1A2, A2A2) at a locus encoding the enzyme peroxidase in Ponderosa pine trees growing at Crater Lake. The observed number of individuals we these genotypes are given below: A1A1 = 135 A1A2 = 44 A2A2 = 11 Calculate the EXPECTED number of individuals with each genotype, as predicted under Hardy-Weinberg equilibrium. Carry out a chi-square goodness-of-fit test on the observed and expected numbers of individual Ponderosa pine trees given. What is the chi-square value...

(Hardy Weinberg Equation) In a population of rabbits, there are 423 A1A1, 1484 A2A2, and 1661 A1A2 individuals. If the enviornment changes so that the homozygous recessive genotype suffers a reduction of fitness where it's fitness is now 0.59 , but the other genotypes are unaffected, what will be the frequency of the dominant allele in the NEXT generation?
