Isolation and characterization of polymorphic microsatellite markers for peacock wrasse (Symphodus tinca)

Abstract

Eight polymorphic microsatellite loci were isolated and characterized for the peacock wrasse (Symphodus tinca), a labrid fish inhabiting the Mediterranean and Black seas. Characterization of 35 individuals from the western Mediterranean indicated a relatively high allelic diversity (mean = 12.4, range 9-17), and observed heterozygosity ranging from 0.65 to 0.91. We found no evidence of linkage disequilibrium between pairs of loci. Two loci showed significant departure from Hardy-Weinberg equilibrium. These polymorphic markers can be useful in most basic population genetic applications. © 2006 The Authors.
