Just Curious

I own a chestnut frame overo yearling that was sired by an APHA smokey Black overo and out of a T.bred bay mare. Yes we got chestnut! So my question is this. Is there any chance he could carry a dilute gene from his sire? If he matures anything like his dam and proves himslef in the show ring he will be keept a stud, but since he's red i wasn't sure if I'd be stuck with just plain RED genectics

Thanks for any input!
