What does $p^2$in the below mentioned Hardy - Weinberg equation indicate?

${}^{}$ {(p+q)}^2=p^2+2\mathrm{pq}+q^2${}^{}$

The correct option is C individuals that are homozygous dominant

Hardy - Weinberg equilibrium is based on the constant frequency of a particular gene's alleles in a population through successive generations.

Hardy - Weinberg equilibrium is expressed as

$p^2+2\mathrm{pq}+q^2$ = 1

$p^2$ represent homozygous dominant

$q^2$ represent homozygous recessive

2pq represent heterozygous dominant
