Face/leg white. Opinions?

Yes, I shall bother people yet again with my shenanigans. I know there are tons of threads like this, but please bare with me c:

Now Reno, bay/brown (I have yet to have him tested if only for the sake of sating my own curiosity), has some white markings that I'm curious about. I know what the different pinto genes do with body white, but I always get confused about leg/face white. I'm the kind of person who needs a very literal explanation of certain things to understand them. I will post pictures, but I will also describe at least his face markings. He has a large star that I call his stingray or Barbaro star, as well as a snip (in case it isn't very noticeable in the photos). What genes do you say are causing his white? I also apologize for the major page stretch.

The markings on the legs are called pasterns, half pasterns or ankles .. just depends how far up the white goes. The face markings are called star and snip.

What could be causing it?, Most probably he is taking after his sire and dam.

lol I know what they're called, but there is a prominent theory that all white markings are caused by one of the pinto genes. In any case, his sire was chestnut with only a blaze. I can't find any pictures of his dam.

Ok.

Have you researched further back in the line?

I can't really see how it's caused by a pinto gene, he has no white above the knee's or belly line?

His dam may of had half pasterns..?

JustAwesome - any white on the horse that isn't from scarring is caused by a pinto gene. Some horses just express it very minimally and have "normal" face and leg markings. Others express it to a louder degree, and have what is considered "pinto" markings. However, they are all caused by one of the several pinto genes.

OP - Your horse probably has sabino. His face white is fairly symmetrical, and fairly narrow within the confines of his face. His leg white is somewhat "messy" and has the typical spear head of a sabino leg marking.

That would mean my mum's horse's white is caused from a pinto gene and everyone's horse who has white also (if they're not an appy etc)?

Chiilaa 10-17-2012 07:02 AM

Yup exactly that :-)

Thank you Chiilaa. I was hoping you'd come over here XD

He also looks bay, not brown to me. He has the rich burnt mahogany coat usually associated with bay and none of the mealiness usually associated with brown.

Yes, but Appys are no exception. Leg and facial white on Appys are due to the same factors as any other breed...
