Ry 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.

Use this new information to determine the parents’ genotypes (indicated by red arrows). then calculate the probabilities that the second male offspring will have each condition. drag one pink label to each pink target and one blue label to each blue target. then use the white labels to answer questions 1 and 2. labels can be used once, more than once, or not at all.
