Will Musk Ox and Bison breed together?

Answer 1

The answer to that is most likely yes, over 95% of all species of animal originated from tropical rain forests. They migrated north and south and adapted to the various biome climates. Elephants adapted long fur during the Ice Age and took on the identity of woolly mammoths.

You can compare the hair on the bodies of humans from the tropical regions to those of let's say Denmark or Sweden, you'll find that even people up in the colder regions have adapted more body hair.

Another adaptive trait for animals that travel to the extreme north from the rain forest, is that they become more black-and-white and color. Where in the rain forest, they are very colorful.

Answer 2

Musk ox and bison are different species entirely, they are no more likely to mate than a horse and camel.
