In a population of 500 sheep in Hardy-Weinberg equilibrium, 80 individuals have black wool while the remainder have white wool. White wool (W) allele dominant over black wool (w) allele.

a) Please calculate the frequency of homozygous dominant, homozygous recessive, and heterozygous individuals in this population.

b)Please calculate the frequencies of black wool alleles and white wool alleles in this population

Answer #1

Let W be the white wool allele and w be the black wool allele; let also p and q be the frequency of allele W and w respectively. Total number of sheeps in the population=500; number of sheeps having black wool=80; number of sheeps having white wool=(500-80)=420

(a) Frequency of homozygous recessive individuals or ww genotype, , so

Frequency of homozygous dominant individuals or WW genotype, and frequency of heterozygous individuals or Ww genotype,

(b) Frequency of black wool alleles, and the frequency of white wool alleles,
