Question

question 22 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
○ bottleneck.
○ gene flow.
○ genetic drift.
○ founder effect.

Explanation:

Gene flow is the transfer of genetic material from one population to another through migration and inter - breeding. Here, a new fish (with different genetic traits, being white) is introduced into a lake population and can breed with the existing fish, which is an example of gene flow. A bottleneck event reduces the size of a population drastically. Genetic drift is the change in allele frequencies due to random chance. The founder effect occurs when a new population is established by a very small number of individuals from a larger population.

Answer:

B. gene flow
