Remember Comico VI?

He IS grey, but a really weird grey. Check out what they wrote about his daughter:" onclick=";return false; Basically, she tested as bay that is heterozygous grey, no silver, but does not have black points. So... thoughts? New type of grey? New modifier of grey?

I didn't know about Comico VI so I looked him up on the older threads. He looks like he only has sabino roaning like the morgan horses Ben's Flying Silverfield and Lippatink's Sealect." onclick=";return false;

The daughter is definitely strange, but she looks wild bay to me. If she tested At A that means she has 2 agouti alleles, so the other is a non-brown agouti that is dominant over its expression.

If she tests ea that's out the window obviously.
BTW I've been looking for the article on ea and haven't been able to locate it again. Does anyone know a link to it? :?:

Threnody Sun, 10/24/2010 - 14:01

Thanks ACC. ^_^

That's why I haven't been able to find it again. Guess it just means that I have to one day buy it. I have several articles from them that I want to read from them but can't :P

I assumed that ea tested like E because the test looks for the recessive e. I didn't think ea would test as e... I dunno, I think her tests are right - especially since they were repeated.

Daylene Alford Sun, 10/24/2010 - 15:02

ea is another red mutation. It wasn't found until some horses who had tested EE had red foals. If I remember correctly it is fairly rare but they do test for it in modern extension tests.

Monsterpony Sun, 10/24/2010 - 15:03

ea tests E because e is a mutation of E. The labs look for the e mutation and, if they don't find a mutation, they call it E. Since is ea is a different mutation from e, they have to look for the ea mutation specifically, otherwise they will list it as E.

Yep, and they didn't start doing that until I think last year some time. She's young enough that she could have been tested with just the "e" test and not "e/ea" test.

I didn't see the grey, but she tested grey after the previous test which tested bay?

accphotography Sun, 10/24/2010 - 19:45

Yeah that caught me too. Very odd situation. I also don't ever remember him being called gray before now.

Third Peppermint Sun, 10/24/2010 - 20:26

I think it's assumed because the mom isn't and Comico does have something going on. He was called bay rabicano but is graying more and more. I'm suggesting a new grey modifier that modifies the base coat. :)

Threnody Sun, 10/24/2010 - 21:51

Comico VIs sire Devoto II is a gray, with literally ALL of his ancestors being gray 5 generations back. So I would not be surprised if Comico VIs sire is homozygous gray.…" onclick=";return false;

That makes Comico VI the slowest graying horse I've ever seen O.O

JNFerrigno Sun, 10/24/2010 - 22:50

Anyone know how recently Comico VI was sold? If he's showing here in Wellington that is my back yard and I can see about getting some photos. I know a few of the Andalusian owners here, so I wonder if they are one of them.

At first glance I would have said she looks like a wild bay, but then I red all her info. That is interesting. And she is absolutely stunning!

Rusti Tue, 10/26/2010 - 00:53

Looks to me like she has some kind of gray that only affects mane and tail. Kinda like flaxen. Just a thought lol.

rabbitsfizz Tue, 10/26/2010 - 10:34

What about Rabicano, wasn't that what was sending the Welsh manes and tails grey, exactly like this filly?
I do like the total lack of the word "rare" in their blurb, and their honesty over how perplexed they are by her colour! Makes a nice change.
I do not see Grey in her, and would like them to test her again at another lab.

Third Peppermint Tue, 10/26/2010 - 10:48

I do actually like this farm, they seem very reasonable and they have excellent photographs and design. :)

The filly's sire was said to be rabicano because of his white ticking on the coat, but he HAS been progressively getting greyer and greyer, although he's greying out more like varnish appaloosa roan rather than grey and it didn't start for a long time after he was born. I think it's Comico's weird greying that makes me feel that the filly could carry the same weird version of grey.

Although, that doesn't mean that they couldn't be rabicano, too. Could explain the silvery mane and tail.

Does anyone know if ea is dominant or recessive to e? Is that possible to tell?

Here's Ferrando, the filly's half-brother (same sire):…" onclick=";return false;
And here's Giorgio, same parents as Ferrando:…" onclick=";return false;

Half sister, bay with some sort of roaning:…" onclick=";return false;

Here's some pictures of Comico VI for reference:…" onclick=";return false;
And Comico's full brother with the same weird greying:…" onclick=";return false;

I STILL think there's something going on with grey...

Its the same as "e" basically.

Eea is black based

eae is red based

eaea is red based.-

Yeh I reckon they must be a REALLY slow type of greying?! Comic in your last pictures does look more obvious grey?

Daylene Alford Tue, 10/26/2010 - 19:38

Does anyone know if the gray tests for the actual mutation or if it tests for the the wild type? If it tests for the wild typeit would be possible for them to have a related mutation. Sort of like At testing as A.

accphotography Tue, 10/26/2010 - 19:57

I too would like to know that as I know of two other horses that have tested positive for gray when I can't understand how... that would explain it.

Threnody Tue, 10/26/2010 - 20:09

Comico does look like a dapple gray now. Considering his breeding he may have had enough polygenic factors suppressing the gray from taking effect till later. From what I've read on the UC Davis site the gray test is direct.

Third Peppermint Wed, 10/27/2010 - 06:48

Keep in mind... there are multiple andalusians names Comico.

The Comico that looks dapple grey and Comico VI are full brothers, but not the same horse. The most recent pictures of Comico that I saw did not look dapple grey, like his big bro.

I'm thinking that the grey test checks for a specific mutation, too.

Now I'm just confused. Could there be a grey modifier?

Threnody Wed, 10/27/2010 - 09:52

Thanks Third Peppermint... I apparently mistook pictures of Comico IV for Comico VI. >.<
I agree that there may be a modifier or several influencing the gray progression.

Though one highly improbable (yet theoretically possible) possibility would be a somatic mutation of the G allele in a very early cellular phase. Gray would still be present in the DNA and show up on a test, but it would be "switched off" from expressing in the individual.
