Abstract_ Background Populational linkage disequilibrium and within-family linkage are commonly used for QTL mapping and marker assisted selection. The combination of both results in more robust and accurate locations of the QTL but models proposed so far have been either single marker complex in practice or well fit to a particular family structure. Results We herein present linear model theory to come up with additive effects of the QTL alleles in any member of a general pedigree conditional to observed markers and pedigree accounting for possible linkage disequilibrium among QTLs and markers. The model is based on association analysis in the founders further the additive effect of the QTLs transmitted to the descendants is a weighted by the probabilities of transmission average of the substitution effects of founders haplotypes. The model allows for non-complete linkage .
