The X Chromosome harbors quantitative trait loci for backfat thickness and intramuscular fat content in pigs

摘要

Genetic markers have been used in experimental crosses in pigs to dissect genetic variation in quantitative traits (e.g., Andersson et al. 1994; Knott et al. 1998; Rohrer and Keele 1998). We reported recently on the search for autosomal quantitative trait loci (QTL) for fatness traits in an experimental intercross between the obese Chinese Meishan breed and lean Dutch White production lines (De Koning et al. 1999; Rattink et al. 2000). In this paper, the analysis to look for QTL on the X Chromosome (Chr) in this cross is presented.
