Another crazy gray with stipes

Is anyone else excited that they bothered to test for gray? I love that owners are getting more educated on colors.

my boss up at college had a grey mare that was also dun (couldn't tell she was dun at this point). She was also a homozygous grey, and they often bred to a dun stallion. Every foal she tossed was a wild thick marked dun striped baby...that went grey. She had retained one of the dun daughters that went grey, that was only heterozygous grey...and you could always tell with her babies just by the dun factor if they were going to be grey or not...LOL..those grey ones were always so BOLD

That is really interesting. So it seems like what we are seeing is that gray can cause dun like stripes on it's own but when paired with an actual dun mutation causes some extraordinarily bold markings. I wonder how true this holds? Now that I'm thinking about it my dad has a dun mare that went gray at least her dam was dun and her sire gray. Her stripes were bold but not what I would call out of the ordinary. No where near as bold as the above filly's or TheSwingHorse's foal.

Mostly just thinking out load on this.

That is interesting. Grey combined with Appaloosa patterns can make some wild-looking spots. Makes it even worse that they eventually turn grey. Same with the duns.

Actually, grey + dun making crazy primitive markings doesn't seem odd to me. Grey works by basically sending pigment producing cells on a pigment production overload. Black foals are born blacker, bay foals are born bay...er and, therefore, I could see dun foals being born hyper dun expressed. It makes perfect sense.

my boss always said a horse born with super dark markings or "adult coat" with her heterozygous greys as their parents would always go grey. She was 100% accurate every time...lol. Some didn't even begin to show any grey hairs for a couple of years, then BAM! And hey, she ended up at least reg. them the right color...lol One of her grey mares was registered as a bay roan, and another as a red dun. She did eventually get that changed on them though to show they went grey.
