Question

A species of daisy has hermaphroditic flowers (i.e., each flower produces both male and female gametes). Researchers genotyped 1,000 individuals at a SNP in three populations. The numbers of each genotype in each population were:

 

Genotype

Population 1

Population 2

Population 3

TT

90

200

50

TC

420

200

500

CC

490

600

450

 

  1. For each population, calculate the allele frequencies and determine whether the population is currently at Hardy-Weinberg equilibrium.
  1. For populations not at Hardy-Weinberg equilibrium, indicate whether there is an excess of homozygous or heterozygous genotypes.
  1. For populations not at Hardy-Weinberg equilibrium, indicate how many generations of random mating it would take for the population to reach equilibrium.
