QuestionMay 30, 2025

Which of the following is an example of gene flow? The movement of people on Earth steadily increases and alters the course of human evolution. An earthquake results in the formation of a canyon, splitting a population of toads apart. A fire drastically reduces the size of a white-tailed deer population . The remaining individuals spread out throughout the remaining forest. A small population of grasshoppers gets blown away and isolated during a storm. The gene pool of the new population is different from the original population.

Answer

The movement of people on Earth steadily increases and alters the course of human evolution. Explanation 1. Identify Gene Flow Gene flow refers to the transfer of genetic material between separate populations. It typically involves the movement of individuals or their gametes, leading to changes in allele frequencies within a population. 2. Analyze Options - The movement of people on Earth altering human evolution is an example of gene flow as it involves the transfer of genes between populations. - An earthquake splitting a population does not involve gene transfer; it's geographic isolation. - A fire reducing population size and spreading survivors is more related to genetic drift, not gene flow. - Grasshoppers being isolated by a storm describes genetic drift due to isolation, not gene flow.
