Szukana fraza: [Opis = "The shape of the mandible of European bison and domestic cattle hybrids and the parental forms was compared by means of a discriminant function. In most cases it was observed that the mandibles of hybrids of backcross generations are similar or identical to cattle. Exceptions were found in F1 hybrids and some backcross generations whose mandibles were more similar to bison than to cattle. The transformation of the mandible shape in hybrids with increasing cattle genes is similar to changes in the skull shape of the same animals."]
