View Full Version : For all the colour experts....

We have a bay T/B mare which we are thinking about breeding to Coppabella Visage (pinto) and we are wondering what the chances of her throwing a pinto/paint foal are.

The mares sire was brown and the dam was bay. There is no information about the stallions parents, but the dams parents were sire bay and dam chestnut.

Can anyone help???

You need to look at the Pinto to see if you will get a pinto, in this case the stallion. If both his parents were coloured than in everycase he should throw colour. If one parent was coloured there is a 1 in 4 chance of throwing colour. There is a great book called 'Horse Colour Explained' by Jeanette Gower, try and find one it is a great read.

Depends on if he is homozygous for colour (pinto) or not.... If he is homozygous then he will always throw colour. If not then you have a 50% chance of getting a coloured foal.

If this stallion is tobiano, he may be either homozygous (always producing tobiano regardless of the mare's colour) or heterozygous (producing roughly 50% tobiano to solid coloured mares).

If both of his parents were tobiano, he has a chance of being homozygous, but this chance is only about 25% if both his parents were heterozygous for tobiano. If only one parent was homozygous and the other heterozygous, he has about 50% chance of being homozygous, and if both parents were homozygous then it's 100% chance.

If he is overo, he cannot be homozygous because homozygous overo is lethal and such a foal dies soon after birth.

Apparently there is a test to determine homozygosity in tobiano. The stallion's owners may have had it done if he was by 2 tobianos. If they say "Yes, we had him tested and he's homozygous for tobiano" then you know your foal will be (heterozygous) tobiano.

Tobiano is a dominant gene so if a horse has it, it shows.

Your mare is safe to breed to any pinto as she has no pinto genes (being TB) and cannot produce a homozygous foal.

Sabino and Splash white are not lethal when homozygous :), and they are part of the overo group. THe only one which is lethal when homozygous is Frame. :)

Splashed white and Sabino are broken colour patterns but they are different to Overo.
Splashed white is believed to be non-viable when homozygous.

Even minimally marked Overos can produce a lethal white foal if bred together, which is why it is best to always breed Overo to solid.

Is there anywhere to see a pic of the stallion? I could probably tell what kind of pinto he is by looking at him.

I just found a pic of him jumping... he looks like a Tobiano or composite Tobiano/Sabino. So 50% chance of a pinto foal, likely to be bay/brown base colour with a small chance of chestnut or black.

Hi! I know I'm a bit behind the times, but here's a curly one for you. We have a black mare with one white foot. We have always bred her to QH's. All her kids were black. nothing else, no matter what the stallion colour was. The last boy is solid chestnut with a white splosh on his arse!!
His grandsire was Peppy's Doc Bar. Apparently he was called paint because of a spot somewhere on one of his hind legs.

ODD! bye for now Esse;)
