Summary Introduction

Introduction:

Hardy-Weinberg equilibrium states that in a population genotype and allele frequencies do not change even after several generations in absence of some evolutionary factor like mutation or migration. According to it, p + q = 1 and p²+ 2pq + q² = 1 where,

p = frequency of dominant allele

q= frequency of recessive allele

p²= frequency of homozygous dominant genotype

2pq = frequency of heterozygous genotype

q²= frequency of recessive genotype
