Question

1. how does the multiplication rule of probability relate to calculating the frequencies of homozygous genotypes in a population?

Explanation:

In population genetics, the multiplication rule of probability is used to calculate the frequencies of homozygous genotypes. If the frequency of an allele in a population is \(p\), the frequency of the homozygous genotype for that allele (\(AA\)) is \(p\times p = p^{2}\) (assuming random - mating and Hardy - Weinberg equilibrium). Similarly, if the frequency of another allele is \(q\), the frequency of the other homozygous genotype (\(aa\)) is \(q\times q=q^{2}\). This is because the probability of two identical alleles coming together to form a homozygous genotype is the product of their individual frequencies in the gene pool.

Answer:

The multiplication rule of probability is used to find the frequency of homozygous genotypes by multiplying the frequency of an allele by itself under the assumptions of random - mating and Hardy - Weinberg equilibrium.
