Solution

The correct option is A p2+2pq+q2=1
The Hardy-Weinberg equation used to determine genotype frequencies is:

p2+2pq+q2=1.

Where p2 represents the frequency of the homozygous dominant genotype.

2pq represents the frequency of the heterozygous genotype.

q2 represents the frequency of the homozygous recessive genotype.

Hence the correct option is
a. p2+2pq+q2=1
