Which of the following statements is most accurate concerning the founder effect?

The founder effect occurs when a small group separates from a larger population and establishes a new population. Because the founders carry only a sample of the original population’s genes, allele frequencies can differ by chance. It is a form of genetic drift, does not increase genetic variation, and is not limited to the Amish. Therefore, the most accurate statement is “It results when a small population breaks away from a larger one.”
