U Question 8 Imagine you are studying ear length in a population of rabbits. Ear length in this population is controlled by a single locus with two alleles (A and a) exhibiting complete dominance. You have determined some characteristics of the population, including the following: 5 pts - The population is very large. - Rabbits with long ears are better able to avoid predators, compared to rabbits with short ears. - There are 100 long-eared rabbits (50 AA, 50 Aa) and 25 short-eared (aa) rabbits. Using this information, you set out to calculate allele and genotype frequencies. Which of the following is TRUE regarding equations you could use to calculate these frequencies? Op+q=1 would not be appropriate to use for this population. O It is appropriate to use p^2 + 2pq + q^2 -1 for this population. O I could calculate the frequency of heterozygotes by adding the frequency of the dominant allele to the frequency of the recessive allele. The sum of the genotype frequencies in this population will equal 1.

Question 9 Imagine you went back in time and observed Darwin discussing his ideas with a colleague. The colleague says there is no evidence for evolution by natural selection because the constancy of species has not been questioned. In other words, there is no evidence that some species go extinct and new ones appear over evolutionary time. Which piece of evidence would Darwin MOST likely use to counter this argument? Artificial selection 5 pts The fossil record Biogeography, the study of the distribution of organisms Homology of forelimb structure
