Unfortunately there are apparently no real true American bison anymore. A sturdy a while ago showed that all American bison in all of North America have varying degrees of cattle DNA. They’re basically all “beefalo”. They are quite different from cattle in many ways, but they aren’t actually really American bison anymore. Those technically are extinct by objective measures, not all that different than if you breed one dog with a different one, the offspring is neither of the parents and also basically nothing at all until some defining characteristics are identified, reproduced and named at least as a sub-breed.

There are several extant herds that have been genetically tested and proven "pure", although they're the minority

  Do you recall anything about where those herds are, because I’ve only seen research showing that all treated herds have identifiable cattle DNA, i.e., https://www.nature.com/articles/s41598-022-09828-z https://www.nature.com/articles/s41598-022-09828-z

    I was told when I worked at Philmont Scout Ranch [1] that they had a pure herd. Other than that, I know Steven Rinella listed a few pure herds in his (excellent) book [2] on the American Buffalo, but I'd have to dig it out to find them for you.

They have less than 2% cattle DNA, sometimes as little as 0.25%. That they were crossbreedable at all though shows they were already highly related.

Bison and beefalo are different animals. Beefalo can't be marketed as either bison meat or beef.

A lot of coyotes are mixed with dogs and wolves too
