Which of the Following Would Not Alter a Gene's Frequency

Question

Which of the following would not alter a gene's frequency in a population?
A) mutation
B) migration
C) random mating
D) inbreeding
E) a bottleneck

Accepted Answer

Random mating does not result in any changes to the gene frequency in a population as there is no influence on which individuals mate with one another. The other options all have the potential to alter gene frequency; mutation introduces new variants, migration brings in new genes from other populations, inbreeding increases the proportion of homozygous individuals, and a bottleneck reduces genetic diversity in a population.
