Consider the following alleles: X1, X2, X3. The different alleles encode enzymes with slightly different ratesof reaction, but are otherwise identical. Consider a population that is sampled for these alleles at two different times. Below are the genotypes for each individual in this population at time 1. For the Time 1 population calculate the allele frequencies and genotype frequencies.(4points)

Time 1: Genotypes for each individual in this population

1XX1, X1X2, X2X2, X2X3, X2X2, X2X2, X1X3, X2X2, X1X1, X2X2, X3X3, X2X3, X2X3, X2X3, X2X3, X1X3, X1X1, X1X2, X1X3, X1X2, X1X2, X1X3, X1X1, X2X1, X1X1, X1X3, X3X3, X2X2, X3X3, X2X2

Answer:

allelic frequencies

• p = 0.34

• q = 0.4

• r = 0.27

genotypic frequencies

• X1X1 = 0.17

• X1X2 = 0.17

• X1X3 = 0.17

• X2X2 = 0.23

• X2X3 = 0.17

• X3X3 = 0.1
