[The characteristics of the reproductive capacity of hybrids of the bison (Bison bison L.) with the domestic cow (Bos (Bos) primigenius taurus). 1. The reproductive capacity of hybrid males].
The hybrid progeny F1 produced by intergeneric crosses of a bison with a domestic cow is characterized by absolute sterility of the male line and fertility of the female line. Crossing of females with fertile males of initial forms permits us to obtain fertile males in the following generations. Any differences in stabilization of spermatogenesis in hybrid males obtained from various crosses and under selection of parental couples were not detected.
