| Background: Improving pork quality can be done by increasing intramuscular fat (IMF) content. This trait is influenced by quantitative trait loci (QTL) sought out in different pig populations. Considering the high IMF content observed in the Durocpig, it was appealing to determine whether favourable alleles at a major gene or QTL could be found. The detection wasperformed in an experimental F2 Duroc × Large White population first by segregation analysis, then by QTL mapping usingadditional molecular information.Results: Segregation analysis provided evidence for a major gene, with a recessive Duroc allele increasing IMF by 1.8% in Durochomozygous pigs. However, results depended on whether data were normalised or not. After Box-Cox transformation,... |
