Which of the following would change the allele frequencies of a population?
A) DNA is stable from generation to generation and does not change, so allele frequencies do not change.
B) Tall people in a population preferentially marry other tall people and do not marry people who are short or average height.
C) A population on an island remains isolated and no one leaves or moves onto the island.
D) All of the answer choices would change allele frequencies of a population.

Question

Quizplus · Accepted Answer

Assortative mating, where individuals with similar phenotypes (like height) preferentially mate, can change allele frequencies by increasing the proportion of homozygous individuals for traits associated with those phenotypes. This can lead to a change in allele frequencies over time, especially if certain traits are selected for or against in the population.
