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.

Many genetic studies, particularly those of recessive traits, have focused on small isolated human populations, such as those on islands. which of the following is a major advantage that isolated populations might provide for the study of recessive traits? a. small populations, especially on islands, are less subject to the confounding effects of natural selection compared to large populations. b. autosomal dominant traits will be more likely to be found in such populations. c. geneticists are more likely to be able to control mating choices in small populations. d. inbreeding, which is more common in small populations, will tend to increase the frequency of recessive conditions, allowing for more cases to be examined. e. small populations likely will experience a high mutation rate and thus produce more genetic variation for study.
