True or False 

If an allele rises in frequency from one generation to the next, it must increase the survival rate of its carriers.

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)? SHOW ALL CALCULATIONS NEAT AND CLEARLY!

The survival to sexual maturity rates for genotypes A1A1, A1A2,and A2A2 are 90%, 85%, & 75%, and their fecundities are 50, 55,and 70 offspring, respectively.

a. what are the absolute fitnesses (W) of these genotypes?

b. Using A1A1 as the fitness reference, what are the genotype’srelative fitnesses (w)?

c. If the frequency of the A2 allele is p = 0.5, what will beits frequency one generation later?
