Question

In Hardy-Weinberg equation, the frequency of heterozygous individual is represented by

• A. p²
• B. 2pq
• C. pq
• D. q²

Answer 1

Answer: (B)

Hardy-Weinberg principle states that the allele frequencies in a population are stable and remain constant from generation to generation.
This can be expressed by the equation
$p^2+2pq+q^2=1$ or $(p+q{)}^2=1$
where, p 1 represents frequency of homozygous dominant genotype, $2pq$ represents the frequency of heterozygous genotype and $q^2$ represents the frequency of homozygous recessive genotype.
