Consider Mendel's pea plants in which a single gene determines whether the peas are yellow from the dominant allele Y or green from the recessive allele y (when both alleles are y). According to the Hardy-Weinberg Principle of Equilibrium, what is the frequency of heterozygous individuals in a population under low selective pressure?

a. p + q = 1

b. p2

c. 2pq

c. 2pq

Explanation:

an individual pea plant could be pp (YY), and thus produce yellow peas; pq (Yy), also yellow; or qq (yy), and thus producing green peas. the frequency of pq individuals is 2pq
