Question

One of the original Amish colonies rose from a ship of colonists that came from Europe. The ship's captain, who had polydactyly, a rare dominant trait, was one of the original colonists. Today, we see a much higher frequency of polydactyly in the Amish population. This is an example of _______.

Answer 1

Polydactyly in the Amish population is an example of Founder effect

Step-by-step explanation:

Founder effect is defined as loss of genetic variation as it occurs when a new population is formed by small number of individuals that are diverge from the a large population.

Polydactyly is an example of these founder effect that causes formation of extra finger which takes place when a a polydactyly man marry within their own community. As a result,genetic variation does't takes place among them and thus the offspring carry recessive genes which leads to this type of rare genetic disease.
