output_of increased spontaneous diploidization abolished mitotic sister chromatid separation increased spontaneous diploidization due to abolished sister chromatid separation 2022-05-16T12:11:03Z A cell phenotype observed in the vegetative growth phase of the life cycle in which heterothallic haploid cells spontaneously form cells with diploid DNA content after failing chromosome segregation and consequently nuclear division. The nucleus is displaced from the cell center by actin cables, preventing chromosome cut and leading to diploidisation. escape from mitotic catastrophe PomBase:mlr FYPO:0007965 vw253 PMID:33506191
