Re: Color Study ('plume' mane - odd pale/two-toned manes)

Wow, a LOT of new information!
I do agree that plume could be a form of flaxen showing on the other colors, it would explain why it doesn't show up on black. However, we come back to the original knowledge that flaxen 'is not supposed to affect any other color then chestnut (not just red hairs, but the coat color chestnut). Even the internet agrees that flaxen affects chestnuts (our admins keep to real life for a lot of this, this is why I reply this). I didn't locate any information about a flaxen gene or a flaxen-linked gene affecting non-chestnuts, but my search wasn't comprehensive, I certainly could've missed something.
The problem I have with this theory however, is that this silvering over the fetlocks will color over the bay-black on the legs. As seen in this horse here:
If I agree with this theory (and I am leaning toward it, insofar as the closest and most likely gene), then we must change the knowledge that when flaxen-plume appears on a non-chestnut horse, it overrides some of the black hairs, at least on the legs.
As for plume being linked to pangare, I have my doubts about this, fairly strongly. There are characteristics of pangare that are not shared by plume. Most obviously, Plume doesn't affect the face or the stomach and Pangare doesn't affect the mane and tail (of course I could be proven wrong). Plus, it sits on top of the pangare when both are expressed. It shows more similar characteristics of dun, the same area colored on the legs as dun and offers a continuation of the dorsal stripe into the mane and tail. However, it doesn't appear to affect grulla (black and dun).
I am wondering now though, if the plume silvering on the fetlocks will also color the feathers with the silver color. Although this won't really add or subtract to what this plume gene may or may not be linked to, it will allow us some further understanding into what it does.
Since it's recessive though, it's not surprising that the new generation of fresh blood didn't pop any plume. In fact, since black is a difficult gene to work with, it's entirely possible that it's not showing, not because it doesn't affect it, but because it's being aggressively stubborn. That being said, at this point in time, until proven wrong, I'm agreeing that plume isn't affecting black. Thus I can also determine that it's unlikely to be connected to silver (regardless of how much it appears similar and I want it to ).
It still could be it's own-standing gene. It hasn't yet proven to be linked to anything, at the same time, there is little to disprove it as well.
We've thus far seen that it will offer itself with and without pangare, with and without dun, on agouti colors. I'm unsure about chestnut still though. It's so easy to call that flaxen and not plume at all, even though it could just as easy to say that it's pairing up and expressing in conjunction with flaxen.
Theories still have weight, but I'm beginning to lean toward it being a stand-alone gene.
By the way, that pseudo-black with the brilliant silver legs is such a sharp-looking horse! I'm sending that one over to the favorites post.
