They always toss in this chestnut.
More apropos is the fact that nearly every bison [Family: Bovidae; Subfamily: Bovinae; Genus: Bison; species: bison] in the U.S. (Wind Cave National Park has the only genetically pure bison herd) carries cattle [Family: Bovidae; Subfamily: Bovinae; Genus: Bos; Species: B. primigenius; Subspecies: B. p. taurus, B. p. indicus] genes.
On top of that, though rare, mules and hinneys have been documented to have bred sucessfully.
[Wikipedia] The surviving species are the American bison, Bison bison (with two subspecies, the plains bison, Bison bison bison, and the wood bison, Bison bison athabascae), found in North America, and the European bison, or wisent (Bison bonasus), found in Europe and the Caucasus. While these species are usually grouped into their own genus, they are sometimes included in the closely related genus Bos,[1] together with cattle, gaur, kouprey and yaks, with which bison can interbreed.
