Sterility is associated with loss of function (LOF) at a gene Z.The gene has 5000 bases where LOF mutations can occur. Assuming thehuman mutation rate is 2x10^-8 per generation. Homozygotes for LOFalleles at Z are sterile, and heterozygotes have mild sterilityissues. The heterozygotes for LOF alleles at Z have 20% fewerchildren than an average individual I the population, but suffer noother ill effects. A) What is the frequency of the Z allele undermutation-selection balance? B) What proportion of the individualsin the population are sterile due to being homozygous for a LOFmutation at Z?
