Question

question 9 1 pts a tourist brings home a small fish and releases it into a nearby lake. this fish is able to breed with fish already in the lake. the lake population is mainly orange and this fish is white. this is an example of

gene flow.

founder effect.

genetic drift.

bottleneck.

Explanation:

Gene flow is the transfer of genetic material between populations. Here, the tourist - introduced fish (with white trait) breeds with the lake's orange - fish population, transferring its genes. Founder effect involves a new population from a few individuals (not here, as it breeds with existing). Genetic drift is random allele frequency change (not due to migration/breeding like here). Bottleneck is population reduction (not applicable). So it's gene flow.

Answer:

A. gene flow.
