Question

In which specific type of small population is the increase in homozygosity due to genetic drift most pronounced?

Options

• Large panmictic populations

• Small inbreeding populations

• Populations with high gene flow

• Populations under strong balancing selection

Answer 1

The increase in homozygosity as a result of genetic drift is especially pronounced in small inbreeding populations. In these populations, the combined effects of drift and inbreeding accelerate the decline of heterozygosity.
