abnormal mitotic sister chromatid segregation lagging mitotic chromosomes 2011-04-19T02:59:38Z lagging chromosomes during vegetative growth chromosome segregation defects, lagging mitotic chromosomes lagging chromosomes during mitotic cell cycle midori FYPO:0000228 Chromosome lagging may reflect a delay in detachment of sister chromatids from each other ('chromatid separation' as defined by GO:0051306), polewards movement (GO:0007079), or both. Consider also annotating to 'unequal mitotic sister chromatid segregation' (FYPO:0003241) or one of its descendants, because chromosomes that lag at anaphase are often missegregated at telophase. A cellular process phenotype observed in the vegetative growth phase of the life cycle in which sister chromatids do not move towards the spindle poles at the same time during mitosis, but instead one or more chromosomes remain distant from the spindle pole after the bulk of the DNA has separated. Mitotic sister chromatid segregation may stop before completing separation of chromosomes, or may eventually be completed. lagging mitotic sister chromatids lagging chromosomes
