查询词典 polymorphism

Using RAPD fingerprinting, we detected changes in PMCs'genomic DNA in Lilium davidii during prophase Ⅰ. The electrophoresis results revealed a specific polymorphism at synizesis stage, but not at other stages or in somatic cells.

Primary culture and subculture were adopted using lung cells of a female Elaphodus cephalophus' embryo. A new karyotype and a pair of big telocentric chromosomes were found. The diploid has 48 chromosomes, and the karyotype formula is 2M+2ST+42T+XX. C-banding analysis shows that these chromosomes are homologous with those reported relevant chromosomes. This article is the first to report the polymorphism of Elophodus cephalophus B-chromosomes and studies it's transmitted mechanism.

采用原代培养和传代培养法，对1头毛冠鹿的胚肺组织细胞进行观察，发现一种新的核型，其二倍体染色体数目为2n=48，核型公式为2M+2ST+42T+XX，出现1对大的末端着丝粒染色体，C-带显示该染色体与已报道的相关染色体同源，首次提出毛冠鹿B染色体多态，对其传递机制进行了探讨。

AFLP marker technique was used to investigate the genetic relationships between 50 accessions of maize and its wild relatives including teosinte, Tripsacum and Coix With twenty one AFLP primer combinations of PstⅠ/MseⅠ, 641 AFLP amplified bands were obtained, including 586 polymorphic bands with an average of 30 52 per primer combination and the polymorphism percentage of 91 4% Cluster analysis using UPGMA method based on the data of AFLP showed that the 50 materials could be divided into...

用AFLP分子标记技术对 5 0个有代表性的玉米及其野生近缘种大刍草、摩擦禾、薏苡材料进行了遗传关系分析。利用 2 1个PstⅠ MseⅠ引物组合检出可辨认带共 6 4 1条，其中多态性带 5 86条，平均每对引物得到 30 5 2条多态性带，多态性 91 4 %。聚类分析结果表明，可以将 5 0个材料分为 3大类，与已有的玉米族分类一致，但与玉蜀黍属内的种间和种内分类存在差异，说明大刍草各种内存在较大的遗传多样性。本实验发现玉蜀黍属与摩擦禾关系比与薏苡的关系更近，但并没有发现玉米与小颖玉米亚种比与其他大刍草的遗传关系更近。

Polymorphism in diploid species G.arboreum was the same as in tetraploid species G.hirsutum,both were 11.84%.

在二倍体棉种中棉的扩增多态性率为11.84%，与在四倍体棉种陆地棉的扩增多态性率相同。
