					A model of correlative variability of AB0 blood groups and a quantitative trait (mad-model) was analysed. Statistics for evaluation of additive and non-additive effects of alleles IA, IB and i on quantitative trait were developed. Restrictions of the model application are discussed. The obtained results may be used in genetic epidemiology for study of sensitivity or resistance to different diseases.
