The founder effect is a phenomena that occurs when a small group of individuals becomes isolated from a larger population. Regardless of what the original population looked like, the new population will resemble only the individuals that founded the smaller, distinct population.Hendry is interested in seeing what would happen if more than two animals were used to create a founding population.
