You are an ornithologist (scientist who studies birds) studyingthree 'at risk' populations of nuthatches (Sittapusilla is one of the bird species).

A local logging company is going to clear a forest of maturepines, the natural habitat of the birds. You have determinedthat there are three distinct populations of nuthatches living inthis forest, known as A, B and C. You only have time to trapone population of the birds to relocate them to a new habitat. Youwant to move the population that would suffer the most if they lostmembers. You do not know the total population of the birds inthis region, but you know the location that you are moving thebirds has the following allele frequency:

Population A: p = 0.7 q = 0.4, total members 178

Population B: p = 0.9 q =0.1, total members 504

Population C: p = 0.5 q = 0.5 total members 56

Population A has 30 birds that are brown, a recessivetrait. Population B has 45 brown variants, and population Chas 20 brown variants. All other birds display the dominantphenotype 'red.'

Which of the following statements would be accurate?

YOU MAY SELECT MORE THAN ONE ANSWER.

Question 21 options:

	All groups would increase in genetic diversity equal.
	Population A would be most the best to relocate to increasegenetic diversity in the new location.
	Population C would be most the best to relocate to increasegenetic diversity in the new location.
	Insufficient information is given to determine which group wouldbe most affected.
	Population B would be most the best to relocate to increasegenetic diversity in the new location.

Question 23 (1 point)

You have collected two species of fish from the Antarcticocean. Your research colleague states the fish are notclosely related to one another.

You find that they possess natural 'antifreeze' molecules thathelp them survive the frigid waters.

Which of the following statements would be accurate?

YOU MAY SELECT MORE THAN ONE ANSWER.

Question 23 options:

	The evolution of antifreeze molecules is likely due toconvergent evolution.
	The evolution of antifreeze molecules is likely due to geneduplication from a recent common ancestor.
	The evolution of antifreeze molecules would be considered ahomologous trait.
	It is likely that these species are sister taxa.
	The evolution of antifreeze molecules is most likely due tonatural selection.

	Gene flow best describes an exchange a host and itsenvironment.
	None of the answers are correct.
	Gene flow best describes an exchange between males and femalesof the same species and population.
