查询词典 polymorphism

Specimen within a species differing from other specimens in consequence of intrapopulational variability (e.g. opposite sexes, castes, gynandromorphs and intersexes, aberrant individuals, age and seasonal forms, variants of noninterrupted variability or polymorphism, differing generations).

The CMS line 9704A, the restorer 8001 and F, population of 9704AX8001 containing 120 individual plants were used for molecular mapping of the restorer gene by bulked segregant analysis. 515 decamer primers with arbitrary sequences were chosen for polymerase chain reaction amplification. It is found that the polymorphism between the parents could be detected by 43. 8% of the primer and one RAPD marker OPL09-76I was tightly linked to the restorer gene of the restorer 8001 with the overcross value of 4.17% and genetic distance of 4. 18cM. The marker was repeatable and easy to score.

以辣椒CHS系9704A、恢复系8001及其组合9704A×8001F_2群体120株植株为材料，利用群分法法进行恢复基因定位，通过515个随机引物的PCR扩增分析，发现43.8％的引物在双亲间表现出多态性，找到一个与辣椒CMS恢复系8001中的恢复基因紧密连锁的分子标记OPL09_(-763)，该标记与8001的恢复基因的交换值为4.17％，遗传距离为4.18cM。

The ISSR loci showed very high polymorphism in three Oxytropis species. The differences among populations were mainly influenced by changes of gene frequencies.
