ABSTRACT Amplified fragment length polymorphism (AFLP) and selective amplified microsatellite polymorphic loci (SAMPL) were used for a survey of genetic changes over three generations and search for sex-specific markers in a breeding program of Chinese shrimp Penaeus chinensis. For genetic survey, a total of 247 and 140 clearly defined bands from 6 AFLP and 4 SAMPL primer sets, respectively, were generated. Both estimated percentage of polymorphic loci (ranging from 41.3% to 47.8%) and average gene diversity (ranging from 0.168 to 0.190) were not significantly different from each ...
