Abstract

Development and characterization of polymorphic microsatellite markers in the gray mullet (Mugil cephalus)

Using an (AG)13 enriched genomic library of Mugil cephalus, 12 polymorphic microsatellite loci were isolated and characterized in a test population; the number of alleles ranged from 2 to 11. The observed and expected heterozygosities ranged from 0.2593 to 0.8966 and from 0.3047 to 0.8454, respectively. Two loci deviated from Hardy-Weinberg equilibrium; linkage disequilibrium among the 12 loci was non-significant. These polymorphic microsatellite loci will be useful for genetic diversity analysis and molecule-assisted breeding of the gray mullet.
