The hardy-weinberg principle is written as an equation: p 2 + 2 pq + q 2 = 1. what does the q represent? frequency of the dominant allele the size of the population frequency of the recessive allele the size of the gene pool

There is no rigid rule, since the equation is symmetric. p and q could be either the frequency of the dominant allele, or the recessive, as long as we keep track of what's what.

However, general practice usually puts the frequency of the dominant allele as p, and leave q for the frequency of the recessive.

the answer is trees if i'm not mistaken
