In the long run, the A2 allele will get fixed and the polymorphism would not remain.
The reason is that A2 has a high fecundity value in spring, which is more than that of A1 (70-50=20 units).
And while A1 has such high fecundity in fall, it is not enough to compensate the difference(70-55 =15 units).
Hence, A2 will get fixed.
However, the same will not happen in the second case as, the fecundity values for both the alleles are symmetrical now for spring and fall. That is, one's high fecundity in spring is exactly compensated by the other's high fecundity in fall.

3. Suppose a species has two generations per year, that adult survival rates of genotypes A,A,...
please answer all questions. 3) In a given population, the egg-to-adult survival rates of genotypes A1A1, A1A2, and A2A2 are 70, 80, and 90 percent respectively, and their fecundity values are 90, 150, and 200 eggs per female respectively. a) Calculate the absolute fitnesses (W) and relative fitnesses (w) of these genotypes. b) Which of these genotypes do you expect to increase in frequency over time? Explain.
