Document Summary

Bio 171 exam 1 review non- approved questions: which of the following statements is/are false, meiosis, acting alone, can change allele frequencies in a population. What specific type of mutation is this: non-synonymous mutation, gene duplication, point mutation, frameshift mutation. E. none of the above are accurate: in sexual reproduction, genetic variation is increased by, crossing over between non-sister chromatids, independent assortment, random fertilization. D. a & b: a, b & c, how many unique gametes could be produced through independent assortment by an individual with the genotype. This could be an example of: incomplete dominance, polygenic inheritance, codominance, a or b. E. b or c: all of the following are advantages of asexual reproduction. Except: fewer risks of getting sexually-transmitted diseases, faster population increases, less genetic variation, fewer risks from predators, less energy, time and resources spent on attracting a mate.
