The Comparative Study on the Genetic Diversity of the Wild and Cultured Haliotis asinina Populations by RAPD Technique

摘要

The genetic diversity of the wide and cultured Haliotis asinina populations was tested by RAPD technique. A total of 55 DNA bands were amplified by 12 effective primers in the wild and cultured H. asinina populations, and an average of 4.58 DNA bands were amplified by each primer. Our results suggested that the genetic diversity of H. asinina was high. The effective number of alleles, the percentage of polymorphic loci, Nei's gene diversity and Shannon's information index of the wild population was 1.5016,78.18%, 0.2808 and 0.4132, respectively. And the effective number of alleles, the percentage of polymorphic loci, Nei's gene diversity and Shannon's information index of the cultured population was 1.4753, 72.73%, 0.2726 and 0.4025, respectively. The genetic diversity of the cultured population was lower than that of the wild population.
