PrometaphaseQuestion 3 of 35 1 PointsIf genetic variability increased, what process likely occurred?A. MitosisB. MeiosisC. None of the aboveD. All of the aboveQuestion 4 of 35 1 PointsA hunter attempted to cross breed a black-tailed deer with a white-tailed deer to obtain bigger antlers in a population. Unfortunately, he found that the hybrid offspring only lived for a few days. Which of the following best describes this outcome?A. PolyploidyB. Prezygotic reproductive isolationC. Sympatric speciationD. Postzygotic reproductive isolationQuestion 5 of 35 1 PointsThe genotype frequencies in a population are 0.60 BB, 0.20 Bb, and 0.20 bb. The requirements of the Hardy-Weinberg principle apply to this population. Which of the following genotype frequencies will occur in the offspring generation?A. 0.36 BB, 0.60 Bb, 0.04 bbB. 0.70 BB, 0.00 Bb, 0.30 aaC. 0.60 BB, 0.20 Bb, 0.20 bbD. 0.49 BB, 0.42 Bb, 0.09 bbQuestion 6 of 35 1 PointsA population of turtles in the Pacific Ocean was composed of 0.4 dark green-shelled turtles (GG), 0.3 medium green-shelled turtles (Gg) and 0.3 light green-shelled turtles. If these turtles entered the breeding season without any evolutionary forces acting upon them, what would the genotype frequencies of their offspring be?A. Not enough information to determine frequencyB. GG = 0.55gg = 0.45C. GG = 0.3025Gg = 0.495gg = 0.2025D. GG = 0.10Gg = 0.81gg = 0.09E. GG = 0.49Gg = 0.42gg = 0.09Question 7 of 35 1 PointsIf an organism has two different alleles of a gene as a result of codominance, then:A. Gamete production will proceed incorrectlyB. The gene must have undergone a mutation during interphaseC. One allele will hide the prese Science Biology
