Incorrect resolution of chiasmata in Meiosis II B. single point mutations during Meiosis II C. nondisjunction events resulting from incorrect resolution of chiasmata in Meiosis I D. improper cleavage of the cohesion complexQuestion 2 "Independent assortment" refers to assortment of sister chromosomes at the metaphase plate in meiosis I assortment of sister chromatids at the metaphase plate in meiosis I assortment of sister chromatids at the metaphase plate in meiosis II assortment of homologous chromosomes at the metaphase plate in meiosis II assortment of homologous chromosomes at the metaphase plate in meiosis I A assortment of sister chromosomes at the metaphase plate in meiosis IIQUESTION 3 A cytogeneticist is studying the cells from an abnormal female monkey. In some cells, she finds that both X-chromosomes are active (i.e. not packaged into a Barr body), although one of the X-chromosomes appears shorter. She also finds that one of the autosomes are packaged as a Barr body, and she suspects that a translocation event might have been involved. By referring to the mechanism of X-chromosome inactivation, explain the observations made by the scientist.
