lagging mitotic chromosomes lagging mitotic chromosomes, with complete sister chromatid separation 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. In this phenotype, both processes are eventually completed, and the overall segregation process likely completes. 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. chromosome segregation defects, lagging mitotic chromosomes, with complete sister chromatid separation lagging mitotic sister chromatids, with complete sister chromatid separation midori 2014-12-02T15:38:56Z FYPO:0004101 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 prior to completion of chromosome segregation. Although one or more chromosomes remain distant from the spindle pole after the bulk of the DNA has separated, mitotic sister chromatid segregation does eventually go on to complete separation of chromosomes. lagging chromosomes, with complete sister chromatid separation during mitotic cell cycle lagging mitotic chromosomes, with complete chromosome separation lagging chromosomes, with complete sister chromatid separation, during vegetative growth
