ABSTRACT
The objectives of this study were: to evaluate the numerical efficiency of Gibbs sampling algorithm in an animal threshold model with single gene effect and to verify a hypothesis about a single locus determining twinning rate in Polish Thoroughbred horse population. The properties of implemented algorithm were illustrated with the use of several simulated data sets. The real data set of 1859 mares with full pedigree information was analysed. For these data the hypothesis has been not rejected. It indicates a major gene segregation for horse twinning rate.
