Question

The Hardy-Weinberg principle is written as the equation p 2 + 2 pq + q 2 = 1. What does p represent?

Answer 1

Proportion of dominant allele.

Answer 2

Answer:

P is the frequency of the dominant allele.

Explanation:

Allele is a variant of a gene, and the allele frequency is the proportion of this gene in a population. This frequency tells us how common is an allele in such population.  

So, the frequency of the dominant allele represents the proportion of the dominant allele in the population.

The letter p is used to denote the frequency of the dominant allele.
