Hweezy Problem

  • q² ( Frequency of Homozygous Recessive Individuals)= .05
  • p² ( Frequency of Homozygous Dominant Individuals)= .61
  • 2pq ( Frequency of Heterozygous Individuals) = .34
  • q ( Frequency of Dominant allele)= .22
  • p ( Frequency of Recessive allele)= .78
  • Number of Homozygous Recessive Individuals in population= 50
  • Number of Homozygous Dominant Individuals in population= 610
  • Number of Heterozygous Individuals in population= 340

Steps

  1. Square root q² to obtain q
  2. Subtract q  from 1 to obtain p
  3. Square p to obtain p² 
  4. Multiply p, q, and 2 to obtain 2pq
  5. Multiply q² , 2pq, and p²  to 1000 ( the population) to obtain the number of individuals of each genotype.
