I was at the grand canyon a while ago (hiking rim-to-rim, btw, 24 miles!) The whole way down I was behind a group of tourists on mules. I had plenty of time to think so I started to play guessing games with the mules, like what kind of cross they might be. The mule right in front of me was completely white, and I started to wonder how that could be? Ever since then I have wondered what kind of genetics could make a mule white.
He had pink skin and white hair. He couldn't be a double dilute of something because of being a hybrid, right?
I will probably never see this mule again, but I am so curious!
