The primary goat of the study was to investigate statistical properties of a mixed inheritance model for the localization of quantitative trait loci (QTL). This is based on the analysis of phenotypic data for the amount of intramuscular fat (IMF) scored on 305 individuals originating from a cross between Duroc and Norvegian Landrace breeds. Marker genotype information is available for F1 and F2 generations. Statistical procedures compared involve: interval mapping; the composite interval mapping; a regression method and a mixed inheritance model accounting for a random animal additive genetic effect and relationship between individuals
