An area surrounded by tall mountains contains a very large, isolated population of green and white peacocks. During the mating season, the male peacocks demonstrate flashy feather displays to attract females, who usually choose green peacocks over white ones. A biology student tabulates the following information. Genotype Plumage Color % of Population Allele Controlled Phenotype FF or Ff Dark green 84% F (dominant) Dark green plumage ff White 16% f (recessive) White plumage Using this information, the student plans to use the Hardy-Weinberg equation to predict the allele frequencies in future peacock generations. Why would her research advisor have a problem with this? The student needs the percent of the population with the Ff genotype in order to find the F frequency. Her research advisor would first want her to find the males' mating success rate for the calculations. The peacocks are sexually selective when choosing mates, so future allele frequencies may drift. Since the peacock population is isolated, its alleles would shift away from Hardy-Weinberg equilibrium.
