A Species of Wildflower Grows on Hillsides in Two Locations

question 2

Multiple Choice

A species of wildflower grows on hillsides in two locations.In the first (location A) ,the population is large and diverse,covering a large section of hillside.In the second (location B) ,a small but diverse population grows at the base of a hillside.Severe storms cause extensive mudslides in both areas,killing a large proportion of individuals in both populations.If you were to survey both locations after the surviving flowers have survived and reproduced for several generations,which pattern would you expect to observe?

• A) Both populations would be large and diverse, retaining all of their original alleles in their original frequencies.
• B) Both populations would be very small and genetically uniform, having lost many of their original alleles.
• C) The population in location A would be large and diverse, retaining all of its alleles in their original frequencies. The population in location B would have reduced genetic diversity and different allele frequencies than it did originally.
• D) The population in location A would be large but would show a reduction in genetic diversity and altered allele frequencies. The population in location B, however, would retain its original genetic diversity and allele frequencies.
• E) The population in location A would be large, while the population in location B would be small, but both would be equally diverse genetically and have the same allele frequencies as one another.
