Step 1
C. mating occurs at random in the population.
Answer
To ensure that allele frequencies remain constant in a population, it is essential that mating occurs randomly. This means that all individuals have an equal chance of mating with any other individual, leading to a stable distribution of alleles over generations.
Random mating prevents any particular allele from being favored based on mate choice, thus maintaining the equilibrium necessary for the Hardy-Weinberg principle, which asserts that allele frequencies will remain constant in a population under certain conditions, including random mating.
