Zoology - Evolution Question with Solution | TestHub

Hardy-Weinberg principle says that the sum total of all the allelic frequencies of a gene is 1 and the possible frequencies of above mentioned genotypes, i.e., AA, aa and Aa are p², q²and 2pq, respectively. So mathematically this statement can be written as
p²+ 2pq + q²= 1, where

$p^2$= Homozygous dominant individuals

2pq = Heterozygous individuals

$q^2$= Homozygous recessive individuals
