abnormal nuclear morphology during vegetative growth large and small daughter nuclei 2018-10-30T13:23:50Z FYPO:0006715 midori large and small daughter nuclei during mitotic cell cycle large and small daughter nuclei during vegetative growth A mitosis phenotype observed in the vegetative growth phase of the life cycle in which the nucleus divides unequally to produce one daughter nucleus that is larger than the other. This phenotype does not necessarily reflect a chromosome segregation defect. It may instead arise from abnormal nuclear envelope assembly, following normal chromosome segregation.
