Webb15 juni 2011 · During meiosis, accurate segregation of homologous chromosomes relies on pairing of homologs to form so-called bivalents that interact with the meiotic spindle as a unit, enabling homologous centromeres to orient to opposite poles (Box 1; Fig. 1).In most eukaryotes, the formation of bivalents requires both homologous recombination and … WebbIn meiosis II, the chromosomes line up and sister chromatids are pulled to the opposite poles resulting in the formation of a total of four haploid cells. This pulling apart of sister chromatids is called disjunction and occurs during anaphase II of meiosis II. Thus the correct answer is option C. Solve any question of Cell Cycle And Cell ...
