Abstract. three-generation family of pig was generated by an intercross between animals of two Berkshire grand sires and nine Yorkshire grand dams (BY), and a total of 525 F2 offspring were produced. The initial genome scan analysis identified suggestive quantitative trait loci (QTL) for fat traits on chromosome 12 (SSC12) (MALEK et al., 2001). Animals that were homozygous for Berkshire alleles had relatively less back fat than those with Yorkshire alleles, and heterozygotes were fattest for these QTL. The objective of this study was to further characterize these SSC12 QTL by mapping five additional genes (PSME3, GRB7, MAC30, RPS6KB1 and TAX1BP3) in the BY family and see if they were associated with fatness traits.
