If a population of early humans was reduced from 50,000 to 500 individuals because of a natural disaster,we might find that the resulting and future populations show,when compared with the original population:
A)no changes in gene frequencies
B)greater genotypic and phenotypic variation
C)less genotypic and phenotypic variation
D)further reduction in population size leading to extinction

Question

Quizplus · Accepted Answer

A population bottleneck caused by a natural disaster can result in a decrease in genetic diversity due to the loss of genetic variation in the smaller population. As a result, the resulting and future populations are likely to show less genotypic and phenotypic variation when compared to the original population.
