Why are the gene pools of small populations reduced compared to those of larger populations?
options:
A). inbreeding
B). lack of advantageous traits
C). lack of suitable mates
D). bottleneck events
D). bottleneck events
Bottleneck events, such as natural disasters or human activities, can drastically reduce the size of a population, leading to a limited number of individuals contributing to the gene pool. This reduction in genetic diversity can increase the chances of inbreeding and limit the availability of advantageous traits, ultimately leading to a smaller gene pool in small populations compared to larger populations.
