A species of daisy has hermaphroditic flowers (i.e., each flower produces both male and female gametes). Researchers genotyped 1,000 individuals at a single nucleotide polymorphism (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 |
a. For each population, calculate the allele frequencies and determine whether the population is currently at Hardy-Weinberg equilibrium
b. For populations not at Hardy-Weinberg equilibrium, indicate whether there is an excess of homozygous or heterozygous genotypes
c. For populations not at Hardy-Weinberg equilibrium, indicate how many generations of random mating it would take for the population to reach equilibrium.
