Applications of pig genome information in livestock production

  • QTL affecting the number of vertebrae in pigs

  • The number of vertebrae in swine which is associated with body length varies thereby affecting productivity. The QTL for the number of vertebrae were detected by linkage analyses using F2 experimental families. Detailed analysis using DNA markers developed in the genome sequence of a QTL region on swine chromosome 1 revealed that a 250-kb region is fixed in the pig breeds with a large number of vertebrae.
