The Amish have a higher frequency of polydactyly (extra fingers) in their community than the general population. This is due to the allele for extra fingers being present in the group that started the Amish community.

The difference in allele frequency is due to genetic flow.

The difference in allele frequency is due to the founder effect.

The difference in allele frequency is due to a bottleneck.

The difference in allele frequency is due to speciation.
