The correct statement about gene flow is the following:
- Gene flow makes allele frequencies more similar between populations.
<h3>What is gene flow?</h3>
It is the process of gene exchange between two populations of the same species, as a result of migration.
<h3>Characteristics of gene flow</h3>
- It involves the spread of new genetic variants between different populations.
- It causes changes in the allelic frequencies of both populations and is a possible cause of evolution.
Therefore, we can conclude that gene flow is an evolutionary mechanism that involves the movement of genes from one population to another.
