henry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.

Answer

Brief Explanations:

Genetic drift has a more significant impact on small populations. The island population likely has a smaller size compared to the mainland population. After the hurricane, the decrease in genetic variation in the island species is likely due to genetic drift. Large populations are less affected by random events like a hurricane - related genetic changes and can recover better. Gene flow involves the movement of genes between populations, which is not the main factor here.

Answer:

B. Genetic drift greatly affects small populations, but large populations can recover.
