They found duplicate fgfr1 genes in two varieties of mirror carp: One had lost 111 bases from the twin gene, and another had a base substitution in the twin gene, both of which had presumably led to fewer scales.

随后他们根据不寻常的特征筛查了发生突变的斑马鱼。其中的一个突变便是几乎全身没有鳞片,这不禁使人想起了镜--为了容易打理而没有多少鳞片的一种鱼--的培育。

The results showed that: The number of loci detected in the German mirror Carp, Japanese crucian carp and F1 were 200、207、218, and the number of polymorphic loci were 63、66、72,and the percentage of polymorphic loci were 31.5%、31.9%、33% respectively. The percentage of polymorphic loci of F1 was considerately higher than that of the parents indicating the rather great genetic variations within the 3 populations.

结果表明:在德国镜、日本白鲫、F1中检测到的位点数分别为200、207、218,其中多态性位点数分别为63、66、72,多态位点比例分别为31.5%、31.9%、33%。F1多态位点高于父母本,表明它的遗传多样性和变异水平最高。

In this paper, population genetic variability and genetic structure of five populations of an important cultivation species, mirror carp ( Cyprinus carpio L.) were analyzed using 30 microsatellite loci. The observed and expected heterozygosity values, polymorphic information content and number of effective alleles ( A e were all determined.

采用30个微卫星分子标记,对5个镜群体的观测杂合度、期望杂合度、多态信息含量和有效等位基因数等进行了遗传检测,根据基因频率计算遗传相似系数和Nei氏标准遗传距离,以 c 2检验估计Hardy-Weinberg平衡,以近交系数和基因流分析群体的遗传分化。

The random amplified polymorphic DNA technique was applied to the genetic analysis of Japanese crucian carp ,German mirror carp and their filial generations for using of 24 random primers selected.
