  1. 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
    1. What is the absolute fitness (W) of each genotype?
    2. Use equation 9 in your natural selection handout to calculate the frequency of the A1 allele in the next generation?

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?

A human population in Africa living under a severe malaria selection has the following relative fitnesses (w) of homozygous genotypes in beta-hemoglobin locus: w11 = 0.75 for A1A1 w22 = 0.85 for A2A2 . Assume that w12 = 1.00 for A1A2 . Using heterozygote advantage concept, determine frequency of the mutant sickle-cell beta-hemoglobin allele (q) in this population assuming that genotype frequencies are at balance (?p = 0; balancing selection). why this population not considered a Hardy Weinberg Population

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.
