Allele Frequency Questions

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.

The allele frequencies of the mouse population in the picture are changing over time. Which is true?

• The population is evolving.

• The population is not evolving.

• The population will go extinct.

• The population's genetic variation is increasing.
