Which animal is a close relative of the horse?

And every year they have a really fun family reunion.

I'm surprised they don't mention that a horse and donkey when bred produce a mule (which is sterile).

how about zebra

jewels, I mules was used for farming, plowing fields for crops. My father had a mule for that purpose. Especially i in the south rural areas. the 50's and 60's.

They can be mate.
