Question: what does the following equation represent explain p2+2pq+q2=1?
Answer: The equation of p2 + 2pq + q2 = 1 represents the genotypic frequencies of a population, when it is in Hardy-Weinberg equilibrium. ... Individual frequencies are represented as p and q such as in a diploid, where p and q represent the frequency of allele A and a respectively. The sum total of all allelic frequencies is 1.
