چکیده
|
Direct sequencing of pcr amplicons was used to identify single nucleotide polymorphisms (snps) in the sansui duck (sansui sheldrake duck) myostatin (mstn) gene exons. in addition,the genetic effects of the mstn gene on slaughter traits were analyzed. the results showed that in the studied sample groups,six snps (g.106g>a,g.120a>g and g.159g>a of exon1; g.5368g>a,g.5389a>c and g.5410g>a of exon3) were found in the mstn gene. the g/a mutation in the g.106g>a snp resulted in the change of codon from ggc to agc,and the coding amino acid from gly to ser. additionally,the association tests between snps and slaughter traits showed that g.120a>g affected the breast muscle percentage and lean meat percentage; and g.5368g>a/g.5389a>c affected the semi-eviscerated weight and eviscerated weight. we conclude that the mstn gene could be regarded as a useful candidate gene for carcass traits in sansui ducks. © copyright 2016 zoological society of pakistan.
