Question

transferring alleles into and out of a population due to migratory habits is called
natural selection
genetic drift
bottleneck effect
gene flow
rewatch

Explanation:

• Natural Selection: The process where traits aiding survival/reproduction become more common in a population over time, not related to migration-driven allele transfer.
• Genetic Drift: Random changes in allele frequencies in small populations, not tied to migration.
• Bottleneck Effect: A type of genetic drift caused by a sharp reduction in population size, not migration-based allele transfer.
• Gene Flow: Defined as the transfer of alleles between populations due to the movement of individuals (migratory habits), which matches the question's description.

Answer:

Gene Flow
