In generation 1, the recessive allele has a frequency of 0.6 and in generation 40, the recessive phenotype has a frequency of 0.36. Is the population is Hardy-Weinberg?

• No, the frequency changed from one generation to another.

• Yes, the frequency changed from one generation to another

• No, the frequency remained the same from one generation to another

• Yes, the frequency remained the same from one generation to another

If there are 400 red flowers, 200 pink flowers, and 100 white flowers. Solve for the frequency of the recessive allele.

• 0.28

• 0.14

• 0.38

• 0.42

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.

If a population of lizards is isolated on an island, with no new immigrants over many years, any new genetic variations are most likely to come from

• recessive alleles

• natural selection

• mutations

• speciation

If all 5 Hardy-Weinberg assumptions are true, a population is said to be in genetic equilibrium. This means

• it is evolving

• it is not evolving

Dog breeding is an example of

• natural selection

• genetic drift

• speciation

• artificial selection

The embryos of two different organisms are observed to have similar features. What is the most reasonable conclusion that can be drawn from this observation?

• The organisms will share these same features as adults.

• These organisms will have the same role in the same habitat.

• These organisms will take the same amount of time to develop.

• These organisms are related by a shared common ancestor.
