与chromosome complement相关的网络例句 [注：此内容来源于网络，仅供参考]

As rice chromosome is very small, it is difficult to identify morphologically the individual chromosome from rice chromosome complement.

水稻染色体形体较小，很难从形态上区分各别染色体。

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。

Interspecies hybridization and backcrossing is a means to transfer desirable genes from one species to another in breeding programs of higher plants. Monosomic alien addition lines can be produced via addition of single chromosome of an alien donor species to the entire chromosome complement of the recipient species.

在高等植物中，以种间杂交和回交把有益基因从一个物种转移到另一个物种为目的育种项目中，单个外源染色体常常被附加到含有受体细胞完整一套染色体中，形成异源单体附加系。
