染色体基因

But this prohibition has caused most of the genes on the Y chromosome to decay for lack of fitness.

这种禁止也导致Y 染色体上的大多数基因退化，在其它的基因组上，被损坏的基因可以通过与另外的染色体交换而除去。

The gene controlling powdery mitdewresistance is preliminarily allocated on the H.villosachromosome 〓 by morphological and characteristic identifica-tion combined with cytogenetical analysis.

将性状鉴定与细胞学分析相结合，基本探明簇毛麦的V〓染色体上带有抗白粉病基因，控制簇毛麦护颖频脊簇状刚毛性状的基因在〓和〓染色体上。

As most Streptomyces promoters are invalid in S. erythraea, the promoter of erythromycin-resistant gene, ermE, and Streptomyces chromosomic integration site, attP, and apramycin-resistant gene, apr from plasmid pSET152 are utilized to construct the expression vector pZMW.

因大多数链霉菌质粒的启动子在糖多孢红霉菌中都不能发挥作用，故利用糖多孢红霉菌染色体上红霉素抗性基因PermE启动子作表达载体启动子，并利用pSET152质粒上链霉菌染色体整合位点和氨朴霉素抗性基因，构建了表达载体pZMW。

Ms-yanshi 9^ ms-80 (6) and ms-90-110, were selected as the materials in the study on gene location of B -type cytoplasmic male sterile lines by using monisomic analysis and nullisomic -tetrasomic analysis methods.

结果表明：二角型不育系主效恢复基因只有一对，位于ChrislB染色体上，在旧染色体以外，不存在二角型不育系的主效恢复基因。

A large number of candidate genes of POF are found on X chromosome and autosomes.

目前已发现在X染色体上和常染色体上多个基因与之相关，文章综述了近年来对卵巢早衰候选基因的突变分析情况，旨在从分子水平分析研究卵巢早衰的发病机制提供基础。

Thirty-three of the genes were on autosomes (chromosomes found in both sexes), and two were on the "X-linked" or sex chromosomes.

其中，33种基因位于常染色体，2种基因位于X染色体。

Female Tigons and Female Ligers both possess a tiger X chromosme and a lion X chromosome, yet only the female Ligers will grow large, this means something must happen to either alter the genes or that the cause of the growth dysplasia lies at least partially outside of the genes.

雌虎狮兽和雌狮虎兽都有一个老虎的X染色体和一个狮子的X染色体，但是只有雌狮虎兽会长成庞然大物，这说明一定有什么事情发生了，改变了每一方的基因，或者狮虎兽的生长异常有基因之外的某些原因。

It was inferred that the sd-t gene was located on chromosome 4 according to the established relationship between chromosomes and linkage groups.

由于Prp-b、lg、Wh基因均位于第4染色体上，因而推定sd-t基因位于第4染色体上，其排列位置可能是Prp-b-sd-t-lg-Wh。

Thomas Hunt Morgan provided evidence that genes occur on chromosomes and that adjacent genes on the same chromosome form linkage groups.

摩根证明不仅基因就在染色体上，而且在同一条染色体上紧挨着排列的基因构成一个连锁群，往往一道遗传。

The short stature homeobox-containing gene, located in the short-arm pseudoautosomal region (PAR1) of the sex chromosomes, is one of the recently discovered genes, which is related to short stature.

位于X及Y染色体的短臂的假常染色体区的矮小同源盒基因是一个近年来发现导致矮小症的基因之一。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
