64 14 What type of selection would lead to an outcome of both small and large sized adults within a population? A. directional selection B. stabilizing selection C. disruptive selection 65 15. If the age of sexual maturation is wide-ranging, and is a highly heritable (non-plastic) trait, what relationship would you expect to find? A. Genotypes differ in the age at which they reproduce. B. Non-genotypic factors such as environmental variation are primarily responsible for the age at which individuals begin reproducing. C. Age of sexual maturation is the only trait that is heritable. D. A high variation in genotype corresponds with a low variation in phenotype 5. 16. Allele frequencies of a population will change from one generation to the next A. under the conditions of negative selection. B. under the conditions of disruptive selection C. under the conditions of stabilizing selection D. all of the above E. A and B, but not 16. The interactions across genes that bring about a phenotype is known as A. phenotypic plasticity B. organism fitness. C. the dominance of the alleles. D. epistasis. 57 18. When flanking regions are the same around an allele, as found across multiple members of the population 58 A. This suggests selective sweep of positive selection for that allele. B. There is no linkage. C. A long period of time has elapsed with neutral drift for the overall region in question. D. Higher levels of recombination occur 19. Which of the following is an instance of homology? A. The presence of a waxy capsule in mycobacteria and the presence of wax in a beehive B. The similar pattern of bone arrangement (ie., humerus, ulna and radius) found in the wing of a bird and the forearm of a mammal C. The absorption of DNA into an Escherichia coli cell from a bacterial lineage of a different species D. The red coloration of a bacterial strain and the red coloration of feathers found on robins. 51 28A drought has altered the prevalent form of nutrition available to a large population of birds on an isolated island in the ocean. Assuming there is phenotypic variation for a bird trait related to nutrient consumption and that this trait is heritable, this situation would lead to A. a higher mutation rate B. natural selection C. artificial selectionExplanation / Answer
