There are 3 T alleles and 7 t alleles in a population. Calculate the frequency of the recessive allele.

• 30%

• 70%

• 10%

• 4%

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.

An allele combination (BB, Bb, or bb) is called a

• phenotype

• genotype

• mutation

• gene flow

The movement of alleles from one population to another is called

• genetic drift

• the bottleneck effect

• the founder effect

• gene flow

Select ALL of the following that violate the Hardy-Weinberg assumptions and would lead to a change in allele frequencies in a population.

• natural selection

• large population

• no mutations

• nonrandom mating

• no migration
