非整倍体的

Trust plans to join a single trust fund the minimum amount of 30 million, more than 30 million, more than part of the amount of 5 million aneuploidy.

信托计划加入一个单独的信托基金的最低金额为30亿美元，超过30亿美元，超过部分的数额为500万非整倍体。

The mitotic error rate in cleavage stage embryos was proven to be higher than the meiotic aneuploidy rate and as a consequence, the genome of a single blastomere is not representative for the genome of the other cells of the embryo.

在卵裂期胚胎这种有丝分裂的错误率被证明是高于减数分裂的非整倍体错误率，因此，单个卵裂球的基因不能代表其他胚胎细胞的基因组。

Consistent with predominantly stochastic gene expression and increased energy demands induced by aneuploidy,the "buffering" canalization processes in Down syndrome would be reduced thereby giving rise to increased variance to less stable developmental pathways such as proliferation.

与非整倍体诱导的主要预测基因的表达和增长的能量需要相一致，Down综合征中的"缓冲"的发育稳态过程将会减少，从而导致像增殖这样不稳定的发育途径的多样性增加。

They are often morphologically distinct from A chromosomes, being smallerand more highly heterochromatic in most cases. B chromosomes do not pair with Achromosomes, and they are inherited in a non-Mendelian way, exhibiting meiotic andmitotic instability and nondisjunction. However, B chromosome DNA is quiteidentical to the corresponding sequence on the A chromosome complement. So far afew B chromosome specific DNA sequence have been identified. Specific DNAsequences on B chromosome have been the attractive research area on Bchromosomes.

现已在千余种植物和近三百种动物中被发现。B染色体与物种中正常染色体不同：独立于整倍体基因组之外，减数分裂时不与A染色体发生联会和配对，细胞分裂后期不分离，非孟德尔遗传，富含异染色质，不含对宿主主要性状有影响的基因等。B染色体DNA的分子组成既与A染色体极为相似，具有A染色体DNA分子组成的一般特征：富含重复序列和转座成分，染色体三大功能组件DNA高度同源；又与之相区别，含有B染色体特异的DNA序列，这些DNA序列可以为探讨B染色体的起源和进化提供有价值的信息。

Both single genes and chromosome segments may be hemizygous; for example, the X chromosome in the heterogametic sex, and whole chromosomes in aneuploids.

单独的基因和染色体片断都有可能是半合子。例如在异型性别中的 X 染色体以及非整倍体中的全部染色体。

The fluorescence in situ hybridization technique has established itself as a powerful improvement over conventional cytogenetic techniques and is now a well-accepted procedure for chromosome analysis and aneuploidy screening.

相对于传统的细胞遗传学方法，原位杂交技术具有很大的改进，已成为一种公认的染色体分析和非整倍体筛选技术。
