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 o...

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 ≈ ...

evolution Correct Answer: a change in a population over time Natural selection Correct Answer: the process by which populations change over time What is necessary for natural selection to occur? Correct Answer: traits within a population vary -some individuals leave more offspring than others (fitness) Mechanisms of evolutionary change Correct Answer: Natural selection, genetic drift, gene flow and mutation Fitness Correct Answer: the ability of an individual to produce offspring rela...
