Strange looking buck - hybrid?

[Blowdowner]

I remember reading that Whitetail does will NOT let a muley mount them but a mule doe will let a Whitetail buck breed her…..either way their offspring is sterile. That buck is hard horned. My guess is if it were a true hybrid it wouldn’t have Nutz therefore it would be a Stag Buck & carry velvet all year…….I dunno

No the sterility does not mean lack of testicles or male hormones it's a chromosome error within the actual sperm or egg.
