Answer:
frequency of the recessive allele
Step-by-step explanation:
The Hardy-Weinberg principle states that when there are no distributing factors present, the alleles and genotype frequencies will remain constant. It's expressed as the equation p2 + 2pq +q2 = 1 where f(A)=p and f(a)=q. Remember recessive alleles are expressed as lower case letters while dominant alleles are upper case letters. So, q refers the frequency of the recessive allele
