What characteristic is common of both a genetic bottleneck and a founder effect?
A) Both encounter a population crash.
B) Both involve a portion of a population becoming isolated.
C) Both involve a decrease in a population's genetic diversity.
D) Both affect the entire population.
E) Both are a type of natural selection. A population's genetic diversity decreases in both a founder effect and a bottleneck.

Question

Quizplus · Accepted Answer

Both a genetic bottleneck and a founder effect involve a decrease in a population's genetic diversity. In a genetic bottleneck, the population is reduced to a small number of individuals, resulting in a loss of rare alleles and a decrease in genetic diversity. In a founder effect, a small group of individuals establishes a new population, which may have only a fraction of the genetic diversity of the original population.
