Question

The Amish of Lancaster, PA. have a higher frequency of an unusual form of dwarfism than the population at large. This is probably due to__________.

Answer 1

This is probably due to the founder effect.

Step-by-step explanation:

The founder effect occurs when a new society or population is set up by individuals from a previously large society thus losing a genetic variation in the process. Since this new population is smaller than the original one, genetic variations are less.

The Amish of Lancaster are a small community whose genetic variations may have been reduced due to the founder effect, thus making them prone to having a higher frequency of an unusual form of dwarfism than the rest of the population.
