My mini mare, Galaxy - Solid Black - is in foal to a splash white sorrel overo with blue eyes. According to ColorCalculator - and me having no knowledge of their genetic potency on either side - the possibilities are:
Black Splash White
Bay Splash White
Sorrel Splash White
All are at 16%, or close to that. It's been a while since I've done it.
None of his foals have had color, but all have had blue eyes. Galaxy's foal that we currently have, Rizer, is a solid bay/dun - but his sire was also solid bay/dun. I say bay/dun because it's too close to call and we haven't had him tested.
Let's take bets on what she tosses, and include a gender 8D
