Pangare does it always mean brown?
I am wondering how many horses are labeled brown because they have pangare morkings? I have seen yet another smokey black horse labeled brown because of pangare markings horse tested smokey black Does the pangare mean the horse carries the At or what? I mean you would have to test it to be sure I have seen sorrels with the pangare too Any thoughts on it?
Brown tends to be more seasonal than bay with pangare. As well as that, pangare seems to like the paler parts of the body to extend further, such as in this filly, spreading it right along her belly and under her chest.
As far as the "smoky black with pangare", well at this stage it is believed that pangare doesn't affect black hair, so it can't be that. Smoky can mimic brown a little, but it is unusual. I think this might be a different thing though that is causing the confusion. If the person reading the test didn't understand the complexity of agouti, and was looking at a Ccr Ee result, they could assume that the horse is black with cream. However, we know that agouti is on its own locus, and so we know that those tests could still be a brown or bay horse with cream.
PetDNA is the place that developed the test. They haven't published a paper yet detailing the differences between A and At, and without that, all the other labs have to research it themselves.
Oh and this filly tested Ee aa Cr/N so does that give you any other clues?
This is the filly
I read that they say no funding for it I say smart buisness move all brown testing has to come to them LOL
Just thought I would add - the other labs don't test for A, they test for a. So a horse that is homozygous for some form of agouti would test as _/_ according to their results, heterozygous as _/a and homozygous for non would be a/a. This means that they are in no way specifying which form of agouti is there, just that there is a lack of the recessive form.
I would want to see her test for myself, and then I would want to retest her. After the retest came back the same, I would contact the various labs and see who is trying to work on pangare and send them some photos and her test results.
She makes me, a layman when it comes to genetics, wonder if pangare can act on dilute black, while it can't act on non-dilute black. Similar to how pearl needs cream to activate.
The whole color genetic thing can really drive you nuts cant itit seems to make up its own rules as it goes along either way it still facinates me
So if I am reading this right, only Brown horses can have pangare? I'm pretty sure my sorrel has it. Or am I reading wrong? ( excuse my stupidity)
