非整倍性

The number of theromosomes per nucleus is characteristic of the species except in aneuploid plants.

除了少数非整倍性的植物，细胞核内染色体的数目是物种的重要特征。

Objective: To explore the reliability of the method PRINS for detection of spermic aneuploidy .

目的：探索应用引物原位标记技术分析精子染色体非整倍性的可靠性。

Objective:To study the centromeric dots variation of HEC1B cells and its relationship with aneuploidy aberration.

中文摘要：目的：探讨人子宫内膜癌细胞HEC1B染色体着丝粒点的变异与其非整倍性畸变的关系。

Cleavage velocity and fragment amount of embryo were related to chromosome 21 aneuploidy.

胚胎卵裂的速度和胚胎碎片的多少与胚胎内部染色体的非整倍性存在着相关性。

Objective To use a rapid method by PRINS for detection of spermic aneuploidy.

目的利用引物原位标记技术快速检精子染色体非整倍性。

The rates of the heteroploidy and aneuploidy rose gradually in the shift of benign- borderline-malignancy, and the same was true for the rat es of mortality/relapse as well as the contrast risk. The nature of ovarian tumors with heteroploidy was much malignant than that with diploidy.

在良性、交界性至恶性肿瘤系列中，异倍体率或非整倍体率明显增加，病死和复发率及相对危险性随之增高；异倍体肿瘤的性质较恶，2倍体肿瘤趋于良性。

Aneuploidy The condition, resulting from nondisjunction of homologous chromosomes at meiosis, in which one or more chromosomes are missing from or added to the normal somatic chromosome number.

非整倍性：在减数分裂的过程中同源染色体不分离而造成的一条或多条染色体的缺失或增加。

Aneuploidy is that cells or individuals possess abnormal chromosome number resulted by nondisjunction during cell division .

非整倍体指染色体分离异常所导致的染色体数目非整倍性改变所得到的细胞与个体。

The results showed that the number of chromosome, which was from the cultured seedlings of meristem tip and the rank seedlings of meristem tip, was not altered, both the number were 2n=16,the hereditary stability of callus and regeneration plant was poor; and the variation percentage of chromosome in callus was 43.4%, among which haploid accounted for 6.7%, triploid accounted for 2.5%,tetraploid accounted for 10%,pentaploid accounted for 4.2%,hexaploid accounted for 3.3%,septuploid accounted for 4.2%,octoploid accounted for 3.3%,dysploid accounted for 9.2%;the chromosome variation percentage of differentiation seedlings derived from callus was11.7%,among which haploid was 6.7%,triploid accounted for 1.7%,tetraploid was 3.3%.

结果表明，茎尖分生组织培养的幼苗及丛生苗遗传稳定，其染色体未发生倍性变异，均为2n=16；愈伤组织及其再生苗遗传稳定性较差，愈伤组织染色体数变异率为43.4%，其中单倍体占6.7%、三倍体占2.5%、四倍体占10%、五倍体占4.2%、六倍体占3.3%、七倍体占4.2%、八倍体占3.3%、非整倍体占9.2%；愈伤组织分化苗染色体变异率为11.7%，其中单倍体占6.7%，三倍体占1.7%，四倍体占3.3%。

The phenomenon of polyploidy and aneuploidy exists in the Genus, in which there are polyploid complex.

对19个分类群作了核型观察，其中16个分类群作了组型分析，结果表明各分类群间核型差异显著，该属普遍存在着多倍性和非整倍性现象，并有多倍体复合体类群存在。
