This requires the removal of all connections between separating chromosomes (sister chromatids) before cells ultimately divide.

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.

In the ring model cohesin holds sister chromatids in position--note this is a topological model, not a binding model.

The second mechanism indicates that chromosome imbalance may occur due to untimely centromere division before anaphase I, where sister chromatids are distributed randomly towards both axis [11].

When male mice carrying the Y chromosome containing inverted loxP sites are mated with females carrying a Cre gene, chromosome loss is induced by recombination which is mediated by Cre present between the loxP sites on sister chromatids during embryogenesis.

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.

The centromere is the part of a chromosome that links sister chromatids. At each centromere binds a multi-protein complex named the kinetochore.
