Question

the introduction of a small population onto an island that results in a limited gene pool for a population best describes

gene flow

population bottleneck

genetic isolation

the founder effect

Explanation:

Gene flow is the transfer of genetic material between populations. A population bottleneck occurs when a population's size is significantly reduced, not specifically due to a small - population introduction to an island. Genetic isolation is the lack of gene flow between populations. The founder effect happens when a new population is established by a very small number of individuals from a larger population, resulting in a limited gene pool. In this case, the introduction of a small population onto an island leading to a limited gene pool best describes the founder effect.

Answer:

The founder effect
