a. What are the genotype frequencies in this population?
b. If the population then experiences one generation in which all individuals
reproduce by selfing, what will be the allele and genotype frequencies in the next
generation? You can ignore the effects of selection, mutation, migration, and drift
in answering this question.
5. The following is an illustration of what is known as the Wahlund Effect. Imagine that you
have two neighboring populations 1 and 2. Both populations are in Hardy-Weinberg
equilibrium for a locus with two alleles (A and a). In population 1, the frequency of the
“A” allele is p = 0.8. In population 2, the frequency of the “A” allele is p = 0.2. Imagine
that you generate a mixed population consisting of half individuals from population 1 and
half individuals from population 2.
a. What are the allele and genotype frequencies for your mixed population?
b. Show that this mixed population is not in Hardy-Weinberg equilibrium and
explain how mixing two populations that are in Hardy-Weinberg can produce a
