Expert Solution
Step 1: p2 + 2pq + q2 = 1 and p + q = 1

According to Hardy Weinburg's equation 

p2 + q2 + 2pq =1 and p + q =1

Where, 

p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population

p2 = frequency of dominant genotype 
q2 = frequency of recessive genotype 
2pq = frequency of heterozygous individuals
