Study on the Genetic Diversity of the Conservation Population in Taimen
摘要
Abstract
The genetic diversity of the taimen conservation population ( Contained 4 groups ) with 29 polymor-phic microsatellite loci .The study showed that in the 332 sampled individuals ,2-13 alleles were detected in each locus,the average effective allele number was 3.961 3,the average observed heterozygosity and expected heterozy-gosity were 0.642 and 0.675 1 respectively,the average PIC was 0.633.The genetic diversity of the 4 groups was B7(F1♀×wild♂3 ×3) exceed B10(F1♀×F1♂3 ×3),B10(F1♀×F1♂3 ×3) exceed B6(wild♀×wild♂3 ×3) and B9(F1♀×F1♂1 ×1) was the lowest.Except the group B9(F1♀×F1♂1 ×1),the genetic distance between B6(wild♀×wild♂3 ×3) and B10(F1♀×F1♂3 ×3) was the farthest,between B7(F1♀×wild♂3 × 3 ) and B10 ( F1♀×F1♂3 ×3 ) with the nearest distance .The clustering result based on the genetic distance showed that B6(wild♀×wild♂3 ×3),B9(F1♀×F1♂1 ×1),B10(F1♀×F1♂3 ×3) clustered as one clade respectively ,the cross breeding groups B 7 ( F1♀×wild♂3 ×3 ) was divided into two clades .This research also discussed the possibility that the endangered animals to maintain the rich diversity in offsprings .关键词
