Question

For a population at Hardy-Weinberg equilibrium, what is the frequency of heterozygotes if p = 0.8?

Answer 1

Ans: 0.32

• Hardy weinberg principle helps in production of genotypic frequencies of a population from its allelic frequencies I am give the relationship between allele and genotype frequencies of a Mendelian population.
• Hardy weinberg principle applies to a population in which there is no natural selection, no mutation or migration, population size is large and there is random mating among population.
• According to Hardy weinberg principle allelic frequencies remains constant from one generation to the next in a population (allelic frequency equilibrium).
• In an infinitely large population allelic frequencies determine the genotypic frequencies of population (genotype frequency equilibrium).
