Question

what process describes the movement of genes between populations due to migration? (1 point) the founder effect. gene flow. natural selection. genetic drift.

Explanation:

To solve this, we analyze each option:

• The founder effect: Occurs when a small group starts a new population, not about gene movement between existing populations via migration.
• Gene flow: Defined as the transfer of genetic material (genes) between populations, often due to migration of individuals. This matches the description.
• Natural selection: Involves differential survival/reproduction based on traits, not gene movement between populations.
• Genetic drift: Random changes in gene frequency, often in small populations, not related to migration - driven gene movement.

Answer:

B. Gene flow.
