Triploidy owing to a non-disjunction event in meiosis 2 will have a preponderance of similar-sized alleles, as two similar sister chromatids separate during this process.

SCEs represent symmetrical exchanges of replicated DNA between sister chromatids.

Scientists from Japan, Europe, and the US discuss the history of mitosis research and the model systems that have played a key role; how threads are produced through chromosome condensation; how sister chromatids attach to each other and to the spindle apparatus; how the spindle microtubules nucleate, elongate, pause, and shrink; how kinetochores and centrosomes serve as anchor and control points; the biochemical elements that coordinate the main regulatory stages of entry into mitosis, sister chromatid separation, and mitotic exit; how cells can mis-segregate and unbalance the genome; the cellular changes that occur during cytokinesis; and the differences between mitosis and meiosis.

Seven markers revealed that the fetus inherited with two maternal alleles and one paternal allele, which prove maternal inheritance of triploidy that occurred due to failure of homologous chromosome or sister chromatids to separate properly in meiosis-I.

Because the kinetochores are directly responsible for segregating chromatids during mitosis, a tempting hypothesis is that the asymmetric segregation is involved in nonrandom segregation of sister chromatids to daughter cells immediately after meiosis.

Accurate chromosome segregation requires that chromosomes be bi-oriented, so we begin testing the model by attempting to describe the orientation of the sister chromatids in mitosis and that of the two synapsed chromosomes in meiosis.

Meiosis in organisms with monocentric chromosomes is always pre-reductional, where the first division is reductional with segregation of the homologous chromosomes and the second division is equational with segregation of the sister chromatids.
