Question: A population of 200 individuals is in HWE. There are two alleles at the "A" locus: A and a.
a) What is the expected frequency of heterozygotes in that population?
b) So, roughly how many individuals are heterozygotes, then?
Question: That same population of 200 individuals goes through a generation of reproduction in which all HWE assumptions are met except for finite population size (so, drift is happening).
c) What is the frequency of heterozygotes in the new generation?
d) How many individuals is that?
