Individual animal models to evaluate a wide variety of genetically determined effects are presented for populations where use is made of new technologies such as embryo transfer, sex determination of embryos and semen, cloning, DNA fingerprinting, gene transfer and genetic markers associated with quantitative traits. The general flexibility of animal models to evaluate additive direct, additive maternal, dominance, cytoplasmic, X-chromosomal and gametic imprinting genetic effects is illustrated. Methods are presented for estimation of the effects of transgenes or major genes jointly with estimation of polygenic effects. Also, implications of use and estimation of effects of exogenous recombinant growth hormone are considered.
