The term "n" refers to the size of a population, that is, the number of individuals in that population. In general, in a sample of n individuals, the frequency of an allele is: A)the number of occurrences of the allele. B)the number of occurrences of the allele divided by n. C)the actual value of n D)the number of occurrences of the allele divided by twice the number of individuals in the sample (2n). E)twice the number of occurrences of the allele divided by n. - Answer-D)the number of...

ASU BIO 345 Exam 1| Questions and answers 2023/24 | GRADED A+ D ≈ 0.49 A population of butterflies comes in three color morphs; orange (A1A1), black (A2A2), or orange with black spots (A1A2). You find that the frequency of orange butterflies is 0.49, and the frequency of black butterflies is 0.36. You do not know if the population is currently in HWE. What would you expect the frequency of spotted butterflies to be, if the population is under Hardy-Weinberg equilibrium? A ≈ 0.42 B ≈ ...

A thin-shelled crab can more readily move to escape a predator than can a thick-shelled crab, but it is more vulnerable to predators that drill through the shell. Because of these opposing forces, shell thickness for many types of crabs has remained within a narrow range over a long time. This would be an example of _____________________________ selection correct answer: stabilizing What is genetic change in a population over time? correct answer: evolution What is the mode of natural...
