The chances of a daughter cell lacking essential genes are less than may be expected since many cells that characteristically divide amitotically are polyploid, e.g.

无丝分裂曾一度被认为是植物体在不正常状态下的一种分裂方式，但研究发现，无丝分裂还是较普遍存在的。

The apical bud of Celosia cristata was immersed in 0.05%, 0.1%, 0.15% and 0.2% colchicine solutions for 12 h, 24 h, 36 h, 48 h respectively and the chromosome numbers of the root tip cells in the regenerated plantlets were examined, which showed that the treatment with 0.15% colchicine solution for 36 h would be the best combination that the polyploid rate could reached 23.3%.
