Abstract
Amplified fragment length polymorphism technique has been applied to detect the genetic diversity and differentiation of three wild Haliotis ovina populations in Hainan province, China. High level of genetic diversity was detected among the populations. The mean effective number of alleles per locus was from 1.2027+0.3090 to 1.3530+0.3404, with an average of 1.2969+0.3338. The percentage of polymorphic loci ranged from 66.54% to 60.36%, with an average of 76.18%. The mean of Shannon's Information index was 0.2870+0.2422, ranging from 0.2026+0.2403 to 0.3397+0.2440. And the average of gene diversity index was 0.1981+0.1767, ranging from 0.1306+0.1686 to 0.2276+0.1791. In general, the genetic differentiation among the three populations was insignificant, the average genetic distance among the three populations was 0.0201, ranging from 0.0087 to 0.0462. The UPGMA dendrogram showed that Yinzhou and Yalongwan first clustered into a group and then grouped with Anyou.
