Answer:
"p" represents the allele frequency of dominant homozygous (AA) individuals.
Step-by-step explanation:
The Hardy-Weinberg principle establishes that, for a given pair of alleles with frequencies p and q, in a balanced Mendelian population, the frequency of the different genotypes in each generation will be in accordance with the expression p2 + 2pq + q2 = 1.
In this equation "p" represents the allele frequency of dominant homoxygote individuals (AA), "pq" represents the allele frequency of heterozygous individuals (Aa), "q" represents the allele frequency of individual recessive homozygotes (aa).
