Question

multiple choice question
which evolutionary mechanism does not change allele frequencies, but changes genotype frequencies by increasing the proportion of homozygotes in the next generation?

assortative mating
natural selection
migration
genetic drift

Explanation:

Assortative mating is a non - random mating pattern where individuals with similar phenotypes or genotypes mate with each other. It increases the proportion of homozygotes in the next generation without changing allele frequencies. Natural selection changes allele frequencies based on fitness. Migration can introduce or remove alleles, changing allele frequencies. Genetic drift is a random change in allele frequencies.

Answer:

A. Assortative mating
