The founder effect occurs when large groups of individuals leave their home population and establish new settlements, mating only among themselves. occurs when small groups of individuals leave their home population and establish new settlements, mating only among themselves. occurs when many members of a population die, resulting in a great loss of genetic diversity. occurs when many members of a population reproduce causing too much genetic diversity within the population. does not occur in nature.

the answer is: occurs when small groups of individuals leave their home population and establish new settlements, mating only among themselves.

For the founder effect to occurs, there need to be a small group of migrants that do not represent the genetic composition in the population that settle in a new area.
