WebbChromosome segregation has been studied by the mutation of genes that are involved in mitosis followed by observation of chromosome behavior. For example, by studying … WebbSynapsis is the process in which homologous chromosomes carefully pair. The pairing allows for an orderly first division to send one chromosome from each pair to separate cells. The close association of the homologous chromosomes also allows for crossing over between non-sister chromatids (Fig.3).

Somatic recombination, as opposed to the genetic recombination that occurs in meiosis, is an alteration of the DNA of a somatic cell that is inherited by its daughter … WebbIn prometaphase II, microtubules attach to the kinetochores of sister chromatids, and the sister chromatids are arranged at the midpoint of the cells in metaphase II. In anaphase II, the sister chromatids are separated. Telophase I and Cytokinesis In telophase, the separated chromosomes arrive at opposite poles. WebbII. Reassortment of non-linked genes III.
