Locating some quantitative genes in the pig

Abstract

Locating genes on the pig genome will facilitate genetic improvement in pig productivity. Substituting portions of the chromosome (haplotypes) with standard haplotypes containing marker genes and observing changes in a quantitative trait can help to locate genes affecting economically important traits.Observations in this study are consistent with a model in which the halothane locus is the site of a series of genes affecting growth rate and appetite.Fatness genes onthe other hand seem to have been at loci away from the halothane locus.
