Human populations native to the Americas have much lower genetic diversity than human populations in Africa. This fact is best explained by

A) natural selection.
B) genetic drift resulting from the founder effect.
C) a reduced mutation rate.
D) larger population size.

Genetic Diversity

The total number of genetic characteristics in the genetic makeup of a species, contributing to its ability to adapt to its environment.

Founder Effect

A form of genetic drift where a new population is established by a very small number of individuals, leading to reduced genetic variation from the original population.

Human Populations

Groups of humans living in a specific geographic area, characterized by shared genetics, culture, and societal structures.
