The figure shows a bar plot of moles from three parks in New York City. Each vertical bar represents genotypes from 18
genomic locations in one animal. The bars are color coded, with similar genotypes represented by the same color.
Population A
Population B
Population C
From the data in the figure, are these three populations genetically isolated from one another?
Incorrect
Population A is isolated from the other two populations.
What environmental factors could explain this?
One park may not be connected to any other park by a greenway.
Only two parks may be connected by greenways.
All the parks may be connected to each other by greenways.
None of the parks may be connected to each other by greenways.
Describe natural selection and give an example of natural selection at work in a population.

REQUIREMENTS FOR NATURAL SELECTION TO OCCUR:
17a. Assuming that both types of pom-poms are present in the population, what do you think
would happen to the pom-pom population if the black forest experienced a prolonged drought
so all the trees died and the habitat became red grassland?
17b. Next, think about an alternative scenario. Suppose that natural selection over many
generations had eliminated all the red pom-poms in the black forest habitat so only black pom-
poms survived. After that, a prolonged drought resulted in this habitat turning into a red
grassland. Would natural selection for pom-pom color occur? Why or why not?
17c. The above scenarios are showing that in order for natural selection to occur
must exist within a trait.

Individuals have different inherited traits, so each individual's chance of surviving predation and reproducing is different. The traits of the most successful individuals become more common in the next generation. Individuals have different inherited traits, so each individual's chance of surviving predation and reproducing is different. The frequency of traits in the generation will be identical to the frequency of traits in the next generation.

- Give typing answer with explanation and conclusion A population of snails has a deleterious mutation (m) with a mutation rate of 0.01. Heterozygotes with this mutation will show the deleterious phenotype and have a selection coefficient of 0.4.
