Meiosis, or reduction division, is a special type of cell division
... In anaphase I of meiosis, the homologous chromosomes (1) disjoin and not, as in mitosis, the sister chromatids. In this process the chiasma bridges dissolve, which so far held together the maternal and paternal chromosomes. Some mutant organisms, where meiotic crossing over occurs only on a limited ...
