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.

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.arrow_forward

What is the frequency of the B3 allele, assuming that there are only 3 alleles in the population? O The frequency of B3 = 0.1 because 0.5 +0.4+ B3 = 1. O The frequency of B3= (0.4)2 = 0.16 O The frequency of B3= 0.9 because 0.5 +0.4 = 0.9 O There is not enough information to determine the frequency of the B3arrow_forward

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. Individuals have different inherited traits, but the II 画arrow_forward
- What can you conclude about genetic variation and population size?

The population follows all other HWE assumptions. FF fitness level = 1.0 Ff fitness level = 0.02 ff fitness level = 1.0 Will heterozygotes be maintained in the population after 100 generations?
