非整倍性

非整倍性是指个体的染色体不均衡或者或者某些染色体比正常人的染色体数目多或者少包括唐氏综合症。

Aneuploidy is a chromosomal imbalance of one or a few chromosomes above or below the normal human chromosomal number of46 , which may lead a child to have abnormalities including Down Syndrome .

而且如Hughes指出的，从一个胚胎中发现1到2个非整倍性的细胞并不意味着胚胎就无法存活。

And , notes Hughes , finding aneuploidy in one or two cells of an embryo does not always mean that the embryo will not be viable .

研究结果表明，紫鸭跖草（Tradescantiareflexa）植物具有较高的染色体不分离自发频率，是一种研究诱发非整倍性的较好体系。

Tradescantia reflexa plant which has high spontaneous frequencies of non-disjunction is an ideal system for the study of aneuploidy induction .

由于可以在不同质量和年龄的卵母细胞之间进行GV互换，人们期望应用GV移植来解决卵母细胞成熟时呈现的遗传或发育异常即老龄妇女卵母细胞非整倍体性的增加。

Because GVs can be exchanged between oocytes of different quality or age , it is expected that GV transfer may be used to solve genetic or developmental anomalies in oocyte maturation , e.g. the increased incidence of aneuploidy in oocytes of women of advanced age .

结合随访认为对出现DNA非整倍体的先天性中胚层肾瘤以单纯切除及定期复查为最好。

For congenital mesoblastic nephroma with DNA aneuploid , simple resection and regular follow up are advisable .

虽然染色体数目异常（少量非整倍体）可能对神经细胞多样性有好处，但是大量的非整倍体会导致进行性的异常及疾病。

Although a low-level of aneuploidy , an abnormal number of chromosomes , may contribute to neuronal diversity , high levels of aneuploidy may result in developmental abnormalities and disease .
