1.Imagine a locus with two alleles, A and a, in a wildpopulation of touch-me-not (Impatiens capensis) plants,which hasboth out crossing and selfing flowers.40 AA, 2 Aa, and 18 aagenotypes are found among 60 individuals.
a.Calculate the allele frequencies p= freq(A) and q=freq(a)
.b.How many individuals of each genotype would be expected ifthe HW assumption were met?
c.Is this population in HWE? Explain your answer.
d.Uh oh,bad year for pollinators!What would be the genotypefrequencies in the next generation if the plant only producedselfed progeny? (Hint: the coefficient of inbreeding for selfing ina diploid is 0.5.This is because the chance of the two alleles inthe selfed offspring being identical-by-descent one generation backis 1/2).
e.Oh no, it looks like the pollinators are gone forever!Whatwould be the frequency of heterozygotes at equilibrium (i.e. aftermany,many generations of selfing)
