State the Hardy-Weinberg principle.

Solution

Hardy-Weinberg principle states that allele frequencies in a population are stable and is constant from generation to generation. The total number of genes and their alleles (Gene pool) in a population remains constant. This is called genetic equilibrium. The sum total of alleleic frequency is 1.
According to the law we get abinomial expression :
$p^{2} + q^{2} + 2 pq = 1$
where
p and q are individual frequencies of allele A and a respectively.
p² represents the frequency of the homozygous genotype AA,
q² represents the frequency of the homozygous genotype aa, and
2pq represents the frequency of the heterozygous genotype Aa
