Question

5 Suppose that you have a large population (>100,000 individuals). At a neutral locus in this population, the allele frequencies are freq(A1) = 0.25, freq(A2) = 0.75. You sample that population to form 100 sub-populations of 20 individuals each. Over the next 40 generations, all these sub-populations go to fixation at that locus. Approximately how many go to fixation for allele A1 vs. allele A2? 75 at A1, 25 at A2 50 at A1, 50 at A2 25 at A1, 75 at A2 It depends on the selective pressures at work

Answer 1

5. answer) it depends on the selective pressure at work.

8.answer) We expect that if both parents participate in raising the young, then both sexes will be under selection to exhibit cues relating to ability to provide and care for offspring.
