grullo with dapples?

Still in her winter coat, but whats with the dapples? I've had her since she was a yearling and have MANY pics of all her different shades. Both sire and dam were grullo. I have been curious about getting her tested. Should I test for cream? What exactly SHOULD I test for?

Only cream? or should I test for anything else. Just for curiosity's sake, as I have no plans to breed in the near future...but maybe one day!

Dun very rarely has dapples on its own and I don't see anything else that jumps out at me about her color. You can always test for pearl and lethal white overo.

[quote="TwinCreeksFarm"]If it's for curiousity, test for cream, extension, agouti, and LWO.[/quote]

hmm... Agouti is what restricts the black to the points right? is there no sense in having her tested for black? I will post the results for the champagne I just purchased when I get home.. he was tested for sable(brown), and agouti, and I am confused on how to read the results. I know he is sable champagne, but I dont understand the agouti results.

TwinCreeksFarm Thu, 04/23/2009 - 15:45

Yes, agouti is what restricts the black to the points. You'd test for black (extension) to see what her status is, because we know that she is black based under her coat. :)
Agouti reads like this:
AA -- homozygous agouti (this horse can NEVER produce a black--or any deriative of black--horse)
Aa -- heterozygous agouti (this horse can produce blacks aswell as agouti horses)
aa -- homozygous recessive, meaning this horse does not carry agouti at all, and can never produce an agouti horse.

I beleive the results for him were Aa and there was a T in there.. I will check and post for certain when I get home!

grullagirl Thu, 04/23/2009 - 16:19

i think the breeder used UC Davis, but not positive. I have the papers at home (im at work for another few hours..yuck) IF I remember correctly, the results went something like Aa/t or SOMETHING like that. lol.

If she were mine, I'd test for Extension, Dun and Cream. (Extension and Dun to see if she's Homozygous for one of both)
I wouldn't bother testing for Agouti as you said both her parents were Black Duns (Grullo/a), which would mean that neither had Agouti to pass on.

[quote="TwinCreeksFarm"]Yeah, but she doesn't look like a grulla to me. :? That's why I suggested agouti.[/quote]

Oh she is for sure.. DId you look at her album? Also, I posted a question on the color genetics about my champagnes test results if anyone can help?
heres more pics showing her color:

TwinCreeksFarm Thu, 04/23/2009 - 20:48

A-ha.. the first and last photos are most definitely grulla, the middle does not look it, on my monitor anyways! :mrgreen: So, yup, no need to test for agouti.

grullagirl Thu, 04/23/2009 - 21:40

the color changes with the season! lol. I am curious about a possible cream gene....which lab would be best do you all think?

grullagirl Fri, 04/24/2009 - 10:41

what about black? The reason I ask, IF I was to breed her down the line, of course I would like to have another grullo, so, if I tested her for Homo black? or test her for red? so confusing.. And is there somewhere I can read about "extensions?" I am lost and want to learn!

Sara Fri, 04/24/2009 - 10:50

Very basically, extension just refers to red and black. Your black-based mare could be homozygous at extension (EE) or heterozygous (Ee) and this is something you can test for. (And will probably want to do if you're trying to produce another grulla) You can read more about it here. http://www.equine-color.info/node/19" onclick="window.open(this.href);return false;

dakotakdq Fri, 04/24/2009 - 22:37

wow they are all stunning!! I :love grullas and yours are lovley!!

I would test as everone has said above - for red/agouti, cream & dun :)

Heidi Sat, 04/25/2009 - 10:11

[quote="rabbitsfizz"]Sorry...why would you test for Agouti???[/quote]
I'm in the same tent at this camp, too.
If the horse is Grulla, and a breeding-result of having two Grulla/Grullo parents... :-? there should be NO agouti at all, right?

[i]Grulla/o is a result of Black + Dun. Not bay and dun, or red and dun. Black, no agouti, and dun. Sometimes you can have a cream in there, for a Smoky Black + Dun and still visibly look Grulla/o. Most places testing for extension will throw in agouti as a matter of course, but if this horse and either parent showed up carrying an agouti, they could not be grulla/o.[/i]

[quote="admin"]Dun very rarely has dapples on its own[/quote]

Really? I see bay dun dappled Fjords all the time. Then again, Fjords are Fjords I suppose...

Monsterpony Sun, 04/26/2009 - 10:07

Cream in Fjords is rare. About 85% of fjords are bay dun and those that carry cream are very obviously different from those that don't.
