If the egg-to-adult survival rates of genotypesA₁A₁,A₁A₂,andA₂A₂are 90 percent, 85 percent, and 75 percent, and theirfecundities are 50, 55, and 70 eggs per female, respectively, whatare the absolute fitnesses(W) of these genotypes?UsingA₁A₁as the fitness reference, what are the relative fitnesses(w)? If the frequency oftheA₂allele is p =0.5, what will be its frequency one generation later? What will bethe allele frequency when the population reaches equilibrium (stopsevolving)?

Here are my calculations Ive calculated fitness on an egg to egg basis how many nextgeneration eggs is each egg likely to produce multiply probability of survival to adulthood by average fecundity to get a per egg absolute fitness Again you could take somewhat different approaches NOTE ALSO in the 2generation examples Ive taken the average number of each offspring for each phenotype as starting point for next generation in other words calculated number of grandchildren as absolute fitness You could do this See Answer
