lagging meiotic chromosomes abnormal homologous chromosome segregation lagging chromosomes during meiosis I FYPO:0004393 midori lagging chromosomes during first meiotic nuclear division A cellular process phenotype in which homologous chromosomes or sister chromatids do not move towards the spindle poles at the same time during meiosis I, but instead one or more chromosomes remain distant from the spindle pole after the bulk of the DNA has separated.
