A mutation causing females to construct lower nests would lead to more offspring C. A mutation causing females to construct higher nests would lead to more grand- offspring D. A mutation causing females to construct lower nests would lead to more grand- offspring E. Answers A & C are both correct 42. Over a period of a few generations : A. If the gene pool was nearly fixed (i.e., at almost 100%) for mutation-B , then alligators homozygous for the mutation-C , would be the best gene transport machines B. If the gene pool was nearly fixed (i.e., at almost 100%) for mutation-A , then alligators homozygous for the mutation-C , would be the best gene transport machines C. If the gene pool was nearly fixed (i.e., at almost 100%) for the mutation-B , then mutation-A , would begin to accumulate in the gene pool D. If the gene pool was nearly fixed (i.e., at almost 100%) for the mutation-B , then mutation-C would begin to accumulate in the gene pool E. None of these answers is correct 43. The mutation that would eventually predominate in the gene pool is: A. mutation-A B. mutation-B C. mutation-C D. mutation-A & mutation-C E. None of these answers is correct EEMB 2 Final Ivory Version: 0 Page: 13 44. Assuming that the alligators reproduced exclusively by brother-sister mating , the mutation (of the choices listed) that would eventually predominate in the gene pool is: A. mutation-A B. mutation-B C. mutation-C D. mutation-A & mutation-C E. None of these answers is correct 45. The best gene transport machine (of the choices listed) would be the alligator phenotype that produced: A. 2 offspring and 16 grand-offspring B. 16 offspring and 2 grand-offspring C. 16 offspring and 16 grand-offspring D. A & C are both correct E. None of these answers is correct Use the following information for the next 5 questions (until you see a solid line): An extensive black lava flow is located in an undeveloped region of Nevada. Lizards on both sides of the lava flow are brown. Lizards living on the sparsely vegetated lava flow are black. In the middle of the lava flow is a large lake surrounded by a narrow band of lush green vegetation. Lizards living in this narrow band of vegetation around the lake are green. All three lizard color morphs are well camouflaged from predation by local predators when the soil or the vegetation matches their color, and lizards rapidly return to soil or vegetation matching their color when moved to nearby areas with non-matching color. A molecular study found that the the color morphs are part of a single clade with a polytomy between the green and black taxa. When raised in zoo cages, black and brown and black and green color morphs interbreed and produce fertile offspring (of intermediate color between that of the parents). In a zoo setting, green and brown morphs do not interbreed and artificial insemination leads to sterile offspring. morphs do not interbreed and artificial insemination leads to sterile offspring....
