Sometimes a restriction in genetic variability is imposed on populations by natural catastrophes such as flooding,earthquake,etc.The surviving individuals reflect only a small,random genetic sample of the population affected.This process is termed
A)mutation.
B)migration.
C)genetic drift.
D)assortative mating.
E)bottleneck effect.

Question

Quizplus · Accepted Answer

The process described in the question refers to the bottleneck effect, which occurs when a population undergoes a drastic and sudden reduction in size, resulting in a small and random sample of the original gene pool being represented in the surviving population. This can lead to reduced genetic diversity and potentially harmful genetic effects. Mutation refers to changes in an individual's genetic information, while migration involves the movement of individuals between populations. Genetic drift is a general term used to describe random fluctuations in gene frequency within a population, while assortative mating refers to non-random mating based on certain traits.
