Question

Identify the mechanism discussed below.


gene flow
The transfer of genes from one population to another

Drives the changes that occur in populations

A permanent change in the DNA sequence of a gene

The random change in the frequency of an allele in a population

Answer 1

Here are the mechanisms that match each description:

- Gene flow — the transfer of genes from one population to another.
- Natural selection — drives the changes that occur in populations (differential survival/reproduction of variants).
- Mutation — a permanent change in the DNA sequence of a gene.
- Genetic drift — a random change in the frequency of an allele in a population.
