用 1 5个随机引物对建鲤基因组DNA进行RAPD分析 ,结果显示 ,建鲤群体内的遗传相似系数为 0 91 81± 0 0 73 8,多态位点比例为 0 41 67,平均杂合度为 0 1 884。表明建鲤种质较纯 ,群体内的遗传变异程度较小。建鲤优良性状产生的分子学基础是等位基因的杂合程度较高
RAPD analysis of Jian carp genomic DNA with 15 random primers showed that the genetic similarity coefficient of Jian carp population was 0 91 81 ± 0 0 73 8 and the percentage of polymorphic loci was 0 41 67. The average heterozygosity was 0 1 884. The result showed that Jian carp was more pure and the degree of genetic variation in the population was smaller. The molecular basis for the excellent traits of Jian carp is the higher heterozygosity of the alleles
