I visited a MuskOx research farm in Alaska. They basiicaly said the same thing. However, they had domesticated them and it looked like it should be doable. I got the impression that the University of Alaska probably was way behind the lower 48 on genetic research. They told me it was because the genetic base was so old it doesn't match todays genome. However, my question is will this prevent one of todays animals from carrying an embryo to term? They really did not give me a definitive answer to that.
