Now I'm sure I have been told before but I can't recall was wondering what causes this on the following horses ok first up a thoroughbred gelding I owned now sold, Oh So Bold (TB registered as King of The Ranges) by Tristram (NZ) is this a bloodmark? on his shoulder? [img]http://i179.photobucket.com/albums/w313/bolana/ohsobold-1.jpg[/img] [img]http://i179.photobucket.com/albums/w313/bolana/ron.jpg[/img] and my QH X ASH filly, what causes the pale shoulder and spots that she has??? first shot is most resent, in summer coat, not so visable, she is also sweaty, [img]http://i179.photobucket.com/albums/w313/bolana/101_2711.jpg[/img] younger shots, more visable [img]http://i179.photobucket.com/albums/w313/bolana/101_1811.jpg[/img] [img]http://i179.photobucket.com/albums/w313/bolana/100_1715.jpg[/img] and a shot of her weanling age on feed that caused just that leg to soot heavily [img]http://i179.photobucket.com/albums/w313/bolana/100_0760.jpg[/img] [img]http://i179.photobucket.com/albums/w313/bolana/100_0757.jpg[/img]

I'm not sure what causes the lighter spots on the palomino, but I've seen it quite a bit. Do they ever change or are they always in the same place?

IMO the Thoroughbreds shoulder is a somatic mutation. I've seen it a bit more in Thoroughbreds than in other breeds and that seems to be the only explanation. There is a BLM Mustang filly with a VERY obvious one on her left shoulder. Quite cool. Honestly, if it were my horse, I'd see if there was a way to test hair from both colors.

thanks ACC
the light patch and spots on the filly are always in the same spots, they don't appear to move at all. Just more obvious at times, does seem to vary with what we're feeding her!

the TB I no longer own he is a few states away now, so I wouldn't be able to test, apparently he had a sister by the same sire who had a very similar marking though I never saw her. It certainly made him very distinctive!

I wonder if there is anything that could make a particular stallion more inclined to sire a foal with a somatic mutation. They're not supposed to be heritable, but a stallion to pass two would be interesting. Maybe that's not what they are, but I sure can't think of anything else

the fact he had a sister by the same sire with a very similar mark was what made me wonder if it was a heritable characteristic? :?

I have seen so many pallys with the lighter patches, id love to know what causes it :)
lovey pics Bolana!

Yes lovely pics of lovely furries :D

The spots look like Ben d'Or spots but instead of being darker than the base coat, they're lighter. Could it be related to cream? I've seen it on buckies too I'm pretty sure.

Sorry Bolana there are lots of things out there that we don't have the answer too as yet but we are trying to get there. I too have seen these sorts of patches on red based horses but do not know what causes it, in the case of the one I knew, it eventually disappeared one day. On the TB it could be a huge Bendor spot or even a Chimera but it is interesting that it is passed on. Thanks for sharing.

I was sent a photo of a bay Welsh mare with a similar large, dark patch. I assumed it was related to sooty.
