Lovely flaxen / sabino / rabicano yearling TB colt ...

[TrueColours]

I had the breeder of this colt contact me yesterday to see if I was interested in purchasing him or if I knew of anyone who might be

He’s by Daylight Savings, and out of Judy’s Green Dancer mare, Dance Until Dawn. His second dam is a full sister to My Darling One, Grade 1 winner. The dam is 17hh and the sire is 16.2hh

He is located in Michigan and if anyone is interested in him at all, I would be happy to pass along the contact information for his breeder / owner

How much credibility does he have for the race horse crowd??? He's such a flashy colt and should mature to a good size as well. His owner, who was heavily into show hunters and jumpers years ago said he is a beautiful, flat kneed hunter mover as well

[springboro]

great female line, and the stud was a good stakes horse from the family of successful stallions Raja Baba and Sauce Boat.

Let him see turf... a lot of grass for this one!

[HeadlessHorseman]

He's got everything going for him it looks like....

I hope he finds a great home...

Oh.. my.. how.. lovely.. is.. he.. Thankfully my penny jar is empty and I have no money and no room for more horses.

[TrueColours]

Isnt he neat?! And nice to know that he has credibility from a racing perspective as well (thanks John as always! )

I know their hope is to see him in a race home. Ive got a few feelers out to a few pinhookers I know - they may see merit in him as well and scoop him up

[madelyn]

He should be called "Rembrandt" or something for being so paint splattered...

I'm glad his pedigree has some marketability for racing... but I wonder, will his color negatively affect him in the buyers market for racing???

I see he is the first in his line (that I can tell) who is unusually colored. IMO he is the first in what will be a continued line (if he is allowed to breed) of dominant whites. I am 100% confident he is dominant white and given his pedigree he must be the original mutation. I wish they would send some hair to Samantha Brooks and let her see if she can locate his particular mutation. I think she would be very interested in him.

Immediately took notice and documented this very interesting case.
The frontal photo is very phenotypically intriguing.
Thank you so much for the valuyable watch.
Great!

I readily admit that I am color challenged, and what I learned about genetics in my biology classes are now swirling about in my rapidly depleting brain cells, but are you saying that this remarkably colored horse is a mutant? Just popped out of the mare with no warning, and wowzers, we need sunglasses to look at him? I thought the color breeders planned matings to get wildly marked TBs. This was not planned? A MUTANT?
And is that not unusual?

Yes and yes. Though honestly all horses have some kind of mutation. A mutation is a cause of every "interesting" color in horses, like cream, or Frame, and all of the whites.

I thought the color breeders planned matings to get wildly marked TBs.

They do.

This was not planned? A MUTANT?

I'm sure the breeding was, but the color was a surprise I'm sure. And yes its because its a mutation.

And is that not unusual?

Not too unusual. All 13 of the DW mutations that they've found have been separate mutations and they've all started fairly recently. The gene they are on mutates fairly frequently.

Not as unusual as one might think. Now there is DNA testing to prove parentage - in the past I'm sure they wouldn't get registered.

There was an example of a 'mutant' colt last year that was written up in Animal Genetics:

H. Holl, S. Brooks and E. Bailey. 2010. De novo mutation of KIT discovered as a result of a non-hereditary white coat colour pattern. Animal Genetics 41; Article available for free at http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2052.2010.02135.x/full

It was published in a special issue called: Horse Genomics and the Dorothy Russell Havemeyer Foundation. Some of the other articles there are interesting as well.

OK, bear with me here while I try to make sense of this. And thank you for your very patient answer.
I'm assuming that this colorful young horse was bred by a color breeder. Was there something genetic in that horse's sire or dam that possibly predisposed it to have colorful markings? Was it bred with the intention to get a white, or a palomino, or one of those other interesting terminologies that are given to the "colored" horses?
If the intention was to get a plain bay with one white sock, like I usually get when breeding one of my mares, then this little colorful horse to me would be highly unusual. If that little horse popped out of one of my mares my farm manager would have had a heart attack.
I guess what I'm asking is, was that horse bred to be hopefully a "color" of some kind, and the color just came out more wild than expected. Like, was the breeder hoping to get a palomino, or a white, and out came those very wild markings, or was it a breeding not for color per se, and this little mutant was the result.

[madelyn]

I believe this particular colt was NOT the result of some planned "color" mating - the sire is Daylight Savings, who is a race sire in Michigan with plenty of runners on the ground. The dam is a Green Dancer mare whose offspring seem to try on the track. Can't find a picture of the mare or the stallion, though. It would be the same kind of total shock as that all white filly that popped out of Deebrand, who was bred to Trust 'n Luck.

Maybe this will help.

There is a large gene complex called KIT. Think of a giant string of beads. Sometimes the order of the beads gets scrambled so instead of the beads being in this order:
1-2-3-4-5-6-7-8-9 They are in this order 1-2-9-8-7-3-4-5-6

This is a change that affects how the gene works.

Within in the KIT complex are a number of white pattern mutations like Roan, Sabino, and Dominant White. All are in slightly different regions of KIT.

The colorful colt looks to have a Dominant White KIT mutation, and he looks to be the first in the family to express this mutation, (or change).

Puchillingui is Dominant White, and Airdrie Apache is most likely Dominant White. The Patchen Beauty horses are DW, with the mutation showing up in Ky Colonel, who looked like a chestnut with high whites, but no, or not much body white.



Dun Central Station has a very nice article on Dominant White and other KIT Mutations.'

Then click on the link for KIT Gene Mutations

Very nice article and over view of Dominant White horses.

Hope this helps.

Albeit this colt seems like a bona fide sabino, he is sporting the atypical pattern rarely seen elsewhere. I am referring to the frontal chest pattern also fashioned by ROYAL MANCHADO. See the latter's photo at:
http://www.pedigreequery.com/royal+manchado

Let me pose a little name suggestion. Why not name him with a name that may somehow evoque his likeness with this extreme rarely seen pattern? A name like "REGAL MANCHADO" may serve the purpose.
