What color options would you get breeding a Red Roan (Bay Roan actually) mare to a Perlino Stallion.

Here is the stallions website: http://www.radicalfrenchgold.com/

I have attached a photo of the mare.

Just curious....

Breeze Web,

You have touched on one of my favorite subjects. I love genetics. There are a lot of unknowns. But by looking at the stallion, and the mare with no DNA posted here is what I came up with.

Putting the stallion For each of the following combonations as:
CrCr for the cream
Aa Hetrozygous for Agouti (Since he has buckskins in his lineage)

Not knowing exactly what the mare is for sure, sometimes they surprise you here are a couple options.

#1 Mare as Red gene Hetrozygous Ee
Agouti hetrozygous Aa
Roan factor Hetrozygous Rr = 25% palomino Roan, 25% palomino, 18.75% either buckskin roan or buckskin, 6.25% smokey blue roan, and 6.25% smokey black

#2 mare as hetrozygous red Ee
homozygous agouti AA
Hetrozygous roan Rr = 25% of one of the following palomino roan, palomino, buckskin roan or buckskin

#3 Mare as Homozygous red EE
homozygous agouti AA
homozygous roan RR = 50% chance of Palomino roan or 50% buckskin roan

#4 mare as Homozygous for red EE, and Hetrozygous for agouti Aa and roan Rr
= 50% buckskin roan or 50% Buckskin

#5 mare as homozygous for red EE, agouti AA, and roan RR= 100% buckskin roan

These options are just that, without knowing exactly what each horse is it is hard. And not knowing the exacts one your mare if she is really a bay roan or a red roan....

Not matter what is bred to that stallion it will come out as some dilution because he carries the double cream gene.

Hope this helps, have fun.

Oh wow thank you for the indepth information! I'll have to print that out and study it.

I'm very grateful you took the time to write that all out, thank you very much.

Lindsey,

Not a problem I love Equine genetics, reproduction and nutrition. One day I will finish school on it all. (after my boys get a little older). I had my mare tested at the end of last year, and was surprised that she carries the agouti gene and she is a palomino tobiano paint. The reason I was not sure on your mare is I know you say she is a bay, so that is what I ran the options as, but registered as a red roan. The only reason I might second guess it is that my friend has a dun mare, anyone who looks at this mare says she is just a dun, but she was registered as a red dun. She has had babies and always thrown palominos but she was breeding her to a bay stallion this year and was concerned about the coloring and if she would need to re-register the mare. She re DNA tested her and the AQHA went back through their records and DNA information and sure enough she may look like a standard dun color to the eye but her genetics don't lie and she is a red dun. Now that she has shed out you look at her points and they are not a true black but that burnt black or dark dark red color.

But the testing center I use has a website and that is where I got my information. It is a fun site to play on. Once I got my mares info back and put hers and the stallions in that she was bred to my results were:

12.5% chance of one of the following
palomino tobiano
palomino
Chestnut tobiano
chestnut
6.25% chance of one of the following
Smokey black tobiano orsmokey black
buckskin or buckskin tobiano
black tobiano or black
bay tobiano or bay

So really it breaks down to (color only not adding tobiano pattern) 25% chance of either a palomino or chestnut color, 12.5% chance of smokey black, buckskin, black, or Bay. We ended up having a Bay Tobiano filly. Go figure we were betting on a chestnut. But we love her anyways

It is a fun site to play with. www.equinecolortesting.com

Then on the left is an offspring color coat calculator.

HAVE FUN

I'm fascinated by the color variations myself and have recently been reading up and trying to wrap my brain around this. My question is this, if a horse is coal black with only a brown muzzle (making her brown) is that from the agouti gene?

The Agouti gene in responsible for putting the black points on a bay or buckskin horse. Which includes the black tipping on the ears, on the muzzle, the black on the lower legs and the black mane and tails.

Seal Brown horses were once thought to be part of the bay family, some believe now that they should be in their own catagory. They say brown is most likely recessive to the bay color and is created when the Agouti gene is on a black horse. At first it was thought that seal brown horses were actually black horse with the Mealy (Pangare' gene). Although research has proved otherwise.

Hope this helped.




PS

The Mealy/pangare' gene is what is responsible for causing the pale red/yellow areas on the "soft spots" of a horse. This includes the lower belly, flanks, elbow area, inside legs, muzzle, around eyes. It is what most of us call the "Mully" look. This is most often seen in mules and burrows, but can be found in any breed and just about any color.

This is sooo much fun Cheryl the answer to your question is YES!

Wow P8ntcrazy, you are an amazing source of information, thank you so very much!!!

Thanks,

Like I said it is one of my favorite subjects.

Bay Roan + Perlino (assuming neither horse is homozygous for black or agouti)

18.75% smokey black (may look black)
18.75% smokey black roan (may look blue roan)
18.75% buckskin
18.75% buckskin roan
12.5% palomino
12.5% palomino roan

You have a separate 25% chance that the foal will be homozygous for black and another 25% chance that the foal will be homozygous for agouti (bay/brown modifying gene).

There is NO chance for bay, black, blue roan, bay/red roan, chestnut, or chestnut roan since one horse is a Perlino. Perlino is homozygous for Creme, which means every foal from that horse will have a copy of the creme modifier.
