The differences between a species and a close hybrid are easier to distinguish when viewed side by side. Between the Yellowstone
Bison and the hybrid bison some differences that are easier to pick out are shape and direction of horns, tails, and body shape and
size. On the hybrid bison, you can really see the influence of cattle in their horns.
