Is It All Rabicano, or is he going Grey?

Are we sure Comico VI is gray?

No, we're not sure.

Comico VI's larger pictures are in this forum: http://forumlesecuriesdescoteaux.aceboa…" onclick="window.open(this.href);return false;

I only see one grey baby by him and the dam is grey. All of the foals from non-grey mares are also non-grey (so far).

Yeah that does looks like gray... and the same odd gray.

Simple solution to this would be to test them with the current gray test just to make sure they have the same mutation. That would narrow it down to a modifier.

Comico IV has been tested negative for grey. He is still the same colour as the photos. Rabicanos do get lighter as they age.

http://www.gazaro.co.uk/stallions/Comic…" onclick="window.open(this.href);return false; this one? negative for grey? wowza if so!

I wonder if that means Comico VI is also not grey since they look so similar. Especially since Comico VI has a foal that tested grey out of a mare that does not have grey...

I reckon Comico IV has got lighter since the spain pictures? Looks more and more grey?

That's a bit mind blowing. It's probably some form of progressive roaning then. It's a dapple gray lover's dream if you can get a horse the looks like that who won't end up going white.

I found some more photos of Comico [b]VI[/b] at: http://tintagelandalusians.com/sold_com…" onclick="window.open(this.href);return false; The lower images can be clicked and enlarged. He doesn't look grey to me, but it is interesting.

I think these two threads need merged: http://forum.equine-color.info/viewtopi…" onclick="window.open(this.href);return false;

If Comico VI had a tested gray foal out of a non gray dam that is making me wonder about the test results on his brother Comico IV. Are there pictures of the dam and foal in question?

A bit random, but sort of pertaining to the thread. What [i]is [/i]the slowest graying horse we know of?

[b]lucera [/b] Just wondering where the info of his test results come from since this was your first post on the forum. ^_^ (Don't know if you're the owner ect.)

If Comico [b]IV[/b] tested negative for gray then I am convinced there is a new mutation at work here. He looks far more gray than his brother who I didn't think was gray to begin with.

I'm wondering too. Rabicano does not cause white like that. Sabino roaning I could see for Comico VI the less white one.

As far as the gray looking brother Comico IV is concerned I'm still not sure. Absolutely no offense to the poster who said he tested negative for gray, but I want more proof that he was indeed tested.

I was following a link about Morgan colors from another thread and came across some images of what they are calling a form of Sabino roaning that actually look quite similar to the darker guy (Comico IV), especially the horse called LIPPATINK'S SEALECT (http://www.morgancolors.com/lipsealect2…" onclick="window.open(this.href);return false;). SLEEPYS SELECT ROSE and BEN'S FLYING SILVERFIELD also show white dappling that nearly mimics a look of a horse going gray (but less so than the previous horse), but they never really get there. The link is http://www.morgancolors.com/sabino.htm" onclick="window.open(this.href);return false; and these three horses (which are related) are about 3/4 of the way down the page. Could this too just be a family that is carrying a unique form of sabino roaning mimicking a horse going gray but never fully graying??

I was thinking of those morgans too ^_^ The sabino roaning would make sense for these individuals. With how dramatic the gray looking one is I'm not sure, but it isn't totally out of the range of believability.

Also noted the inclusion on the morgans of the note that they had white hairs at the tailhead, but the lower tail stayed dark (unlike a grey horse), which appears on both 'Comicos' as well I think (obvious on the darker one but can't find a clear shot that shows the top of the tail on the lighter one)

Looking back at the morgan forms of expression it it seems like the same effect. One 3/4 hind picture of him has the white only on the tail base.

I tend to think it's a new rabicano mutation, that includes the Morgans and the young mare with the roaning mane and tail. It just does not look gray to me or sabino - being it is not very progressive like gray is usually, is another point towards rabicano - and of course the key is the white top of the tail. Very interesting!
I think gray must be a very rare mutation since as far as I know all grays go back to one horse - but we have several roans already. All are placed on KIT and if rabicano roan might be also on KIT that would explain the variety since KIT is a mutation wonderland...

Those Morgans really do remind me of the Comicos. I wonder if maybe there's some sort of recessive gene that is hiding and has turned up in both the Andalusians and the Morgans. I wouldn't be surprised if they had a common ancestor somewhere a long the lines. I'm not ready to buy that its sabino, grey, OR rabicano quite yet.

Although, I'm still weirded out about that filly testing grey. Neither parent is "grey."

I like the idea of it being on KIT, though! With all of the dominant whites we're turning up with I wouldn't be surprised if there are other things hiding.

Despina testing gray is really [u]really [/u]strange. Its making me wonder how many more Comico VI's offspring may test for gray but not appear gray. Its really strange since to my knowledge the gray test is a direct test of the gray mutation.

Honestly if Comico VI may likely test positive for gray (because of his daughter Despina), I don't think I beleive Comico IV tested negative for gray.

Though in all honestly I am still extremely confused about what it may or may not be, but the filly testing positive for gray is our best bet for a lead.

It is possible also that there is a "gray suppressor".

That's what I'm thinking may be a good possibility.

Since both Comico's are full brothers the sire may have passed on gray (him being an obvious gray and all) and the dam could have passed on a suppressor to both offspring. And then Comico VI could have passed on both gray [u]and [/u]the suppressor to his daughter Despina. Her testing black based but not appearing to be so is a whole other story. (could be caused by whatever the sire has, or be ea, or wild bay, or magic [size=50]kidding I swear[/size])

If the filly didn't test positive for gray I'd completely support it simply being the KIT pattern theory for this family. I still think it is a very likely possibility for the Morgans because the ones who express it have no gray in their pedigrees at all. Comico IV the very dappled light one has very light legs compared to the morgans though.
