If the egg-to-adult survival rates of genotypes A1A1, A1A2, and A2A2 are 90 percent, 85 percent, and 75 percent, and their fecundities are 50, 55, and 70 eggs per female, respectively, what are the absolute fitnesses (W) of these genotypes? Using A1A1 as the fitness reference, what are the relative fitnesses (w)? If the frequency of the A2 allele is p = 0.5, what will be its frequency one generation later? What will be the allele frequency when the population reaches equilibrium (stops evolving)?

Suppose a species has two generations per year, that adult survival rates of genotypes A1A1, A1A2, and A2A2 are identical, and that the fecundity values are 50, 55, and 70 in the spring generation and 70, 65, and 55 in the fall generation, respectively. Will polymorphism persist, or will one allele become fixed if fecundity values are unchanged for many years? What if the fecundity values are 55, 65, 75 in the spring and 75, 65, 55 in the fall?

In a population of 10,000 beavers, three genotypes, A1A1, A1A2, and A2A2, have different probabilities of survival to reproductive age lA1A1 = 0.5; lA1A2 = 0.8; and lA2A2 = 1.0. At time (t) the frequency of the homozygous recessive individuals = 0.25. Natural selection resulting from differences in survival to reproductive age is the only form of evolution occurring in this population—assume 2m = 5 for all genotypes What is the absolute fitness (W) of each genotype?

The fitness of the A1A1, A1A2, and A2A2 genotypes are 1.2, 0.9, and 1.0, respectively. Calculate the selection coefficient and heterozygous effect. What kind of selection is this? Where will the population ultimately end up in terms of allele frequencies?

Part I. You are investigating the evolution of cuticle color in a scarab beetle inhabiting a desert. Coloration is determined by a single gene A with two alleles: A1 codes for a dark brown color, and A2 codes for a grey color. Since the alleles are incompletely dominant, heterozygotes are tan. Therefore the heterozygotes are almost invisible on the sandy desert floor, while homozygotes are more visible and thus more susceptible to predation. Questions: (a) Based on the given information,...
