Final answer:
In the Hardy-Weinberg formula, p^2 represents the frequency of homozygous dominant individuals.
Step-by-step explanation:
In the Hardy-Weinberg formula, p^2 represents the frequency of homozygous dominant individuals. If p represents the frequency of the dominant allele, then p^2 represents the probability of an individual having two copies of the dominant allele. This means that p^2 represents the frequency of individuals who are homozygous dominant for a particular trait.
