â¢In silico identification and analysis of SNPs mapping a central region of SSC2â¢Association study of SSC2 genes with carcass and meat quality traits in pigsâ¢Detection of significant markers for fat traits and pH1
Association mapping of the central part of porcine chromosome 2 harboring QTLs for carcass and meat quality traits was performed with 17 gene-tagged SNPs located between 44.0 and 77.5Â Mb on a physical map (Sscrofa10.2) in Italian Large White pigs. For the analyzed animals records of estimated breeding values for average daily gain, back fat thickness, lean cuts, ham weight, feed conversion ratio, pH1, pHu, CIE L*, CIE a*, CIE b* and drip loss were available. A significant QTL for fat deposition (adjusted PÂ =Â 0.0081) and pH1 (adjusted PÂ =Â 0.0972) to MYOD1 at position 44.4Â Mb and a QTL for growth and meatiness (adjusted PÂ =Â 0.0238-0.0601) to UBL5 at position 68.9Â Mb were mapped. These results from association mapping are much more accurate than those from linkage mapping and facilitate further search for position candidate genes and causative mutations needed for application of markers through marker assisted selection.
