In this study,104cherry valley ducks,133Sansui ducks and100Xingyi duckswere used as research materials, the genetic effects of duck MyoD1, SCD1and DRD1gene variation on meat quality and serum biochemical indices were researched usingPCR-SSCP and DNA direct sequencing technology, and the gene Polymerization indifferent Polymorphic sites and different genotypes in different Polymorphic loci wereanalyzed. In order to find out the molecular genetic marker assisted selection siteswhich had positive impacts on se...
