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?

Question

Quizplus · Accepted Answer

The frequency of heterozygous individuals in a population under low selective pressure is represented by the formula 2pq, where p is the frequency of the dominant allele and q is the frequency of the recessive allele. Since there are only two alleles, p + q must equal 1, meaning p = 1 - q or q = 1 - p. Therefore, given that the dominant allele Y is represented by p and the recessive allele y is represented by q, the frequency of heterozygous individuals would be represented by 2pq.
