WebAug 8, 2024 · Mitotic nondisjunction can occur due to the inactivation of either topoisomerase II, condensin, or separase. This will result in 2 aneuploid daughter cells, one with 47 chromosomes (2n+1) and the other with 45 chromosomes (2n-1). Nondisjunction in meiosis I occurs when the tetrads fail to separate during anaphase I. Webchromosomes, one from each gamete. Remember that a life cycle is a “complete sequence of phases”. It is thus necessary for the zygote-phase to be connected to the gamete-phase. A transition from a cell with two sets of chromosomes to one with a single set is thus needed. Simple! The zygote only has to be divided in two cells.
