Agouti
OK, just been "trolling" the gallery to pick up some info I needed for an article- am I missing something about Agouti- why is it not mentioned? And...Pangare affects Bay and Chestnut?? Pangare also affects Black, surely?? Luckily, none of this affects the article, but the missing Agouti is puzzling me...

Thanks for that- I was

Thanks for that- I was confuddled because it was not listed as a modifier and I thought maybe you knew something I did not (new that is!!)

Nope. Pangare does not appear to affect black.

OKs. thanks for that...

OKs. thanks for that...
Any thoughts on why it affects black base (ie bay) and not black itself?

Whoa....Pangare only affects

Whoa....Pangare only affects Red????No, that cannot be right as all Exmoors are Bay and all Exmoors (with a few exceptions) are Pangare...
What am I not understanding here?

I mean it affects the red

I mean it affects the red parts of a bay. It doesn't seem to affect black horses or the black points on a bay. Think of it as the opposite of silver. Silver affects black and the black parts of a bay. Pangare affects red and the red parts of a bay.

You mean it affects Black +

You mean it affects Black + Agouti, but needs the Agouti on Black to express? And does not express on Black without Agouti?(as Exmoors could no way be described as having red body colour...)

It affects phaeomelanin in

It affects phaeomelanin in certain body areas. It does not affect eumelanin. So yes, it affects horses that have E at extension and have A or At at Agouti.

Just to make things even more confusing, it is possible what we call pangare in bay horses is just an extreme lightning affect caused by At. However, I have seen photos of a very red looking bay with pangare markings.

^ Exactly. You can see this

^ Exactly. You can see this at work by comparing pangare bays and pangare chestnuts. You will see that the legs and manes on pangare chestnuts are lightened, while the black pigment on bay's manes and legs are unaffected.

It would be interesting to see if any form of pangare ever becomes testable in horses. I know it donkeys the gene for the lack of pangare was isolated.

I wonder if it's on the same

I wonder if it's on the same gene as Urajiro in dogs?

If it was caused by At then

If it was caused by At then all the Exmoors would be Brown......

Aren't most if not all

Aren't most if not all Exmoors brown? I seem to remember someone...maybe Maigray...commenting on how a black one couldn't be registered or am I confused?

As far as I know they are

As far as I know they are Bay, but they may test At- that I do not know. I do know there are no blacks- it is the ones without Pangare that cannot be registered.
