homozygous grey stallion?

[kathya11]

A couple of weeks ago, I was trolling the pedigree database and found a notation about a homozygous grey stallion. I wasn't able to print out the pedigree, I can't remember the name, and for the life of me, it's driving me absolutely crazy.

I -think- it was an *Herbager line stallion, but it's not Grey Dawn or Vigors.

Does this ring any bells for anyone?

There are many cases among them, including various top notch sires and less reknown names. Here a few:

Thanks, Jorge. It -might- have been Al Hattab -- he's the only one of those listed who has the homozygous grey notation in his information. It definitely wasn't any of the others -- I wasn't looking at those pedigrees.

But something makes me think there was an *Herbager-line stallion out there who's homozygous grey.

That's it! Thank you!

It's nice to know I'm really not cgoing crazy...

On the other hand the following sire was not homozygous yet came from a heavy collection of grays:

Next to pure white grey is a dominate clor....rule of thumb you breed a grey to anything you will get a grey. Now does not have to be born grey.....my dapple grey stud was born sorrel and roaned his first year and grey by the time he was 2....I knew he would be grey as his sire was grey......I have seen once in a blue something not turn grey coming from a grey but is very rare.

AQHA did a huge write up some years back on this....was very interesting. So aside from true whites, pink everything, grey will dominate the color.

There was a paper published a couple of months ago, where they found the location of the gray gene. It is a dominant, which means that if the horse has it it will go gray, modifying the base coat. And should show up 50% of the time, when one parent is gray. 100% of the time when one parent carries two copies of the gray gene.

According to the paper, the gray gene accelerates pigment production, which darkens the base coat, this in turn burns out the pigment producing cells and the hairs then turn white.

Verglas is an emerging one.

My experience counters this. For two years in a row I bred my dark bay TB mare Easy Greasy to the grey QH stallion The Last Captive. Got a filly both times. The first is roaning/greying, the second a long three year old has no signs of grey at all.

Your experience counters it because it is wrong!

[xfactor fan]

Believe it or not, both of you may be correct.

A stallion carrying one copy of the gray gene will when bred to non-gray mares average 50% gray, 50% non-gray.


A stallion with two copies will sire nothing but gray no matter the color of the mare.

Both sets of observations are correct.

Well yes both those things are possible, but the assertion that "if you breed anything to a grey you will get a grey" is plain wrong.

[Georgerz]

You can even breed two grays and get a chestnut or bay/brown foal.

Here is a good talented example:
