Smoky Black? or ??

My mare foaled the other day and to my surprise I got an overo out of a Tobiano.

The mare is black/white (parents are unknown)

Sire is a solid buckskin out of a buckskin mare and a bay stallion

 

Not sure if the foal is black, smoky black or buckskin.

 

Thoughts?

Awww, cute foal!

I'm guessing smokey black or maybe buckskin. I can only recall seeing two buckskin foals; one was born looking like a normal light buckskin, the other (a sooty buckskin) born looking like a bay. My vote is with the smokey black.

I think smokey brown... But wouldn't be shocked if it was smokey black. Your result is why ALL stock horses should be tested for OLW before breeding, as obviously one of the parents carries it and you didn't know. Most likely your mare, but there are cases of solid colored horses having frame.

Cute, cute baby.

Actually my mare is a Tovero. Not tobiano as I originally suspected. just because there is an overo gene doesn't mean she's a carrier of lethal white, she just threw the overo color instead of the tobiano pattern. The sire is not paint at all. Totally different breed. No point in testing unless I was gonna breed her to an overo. Colt will be gelded as well so no need in testing him.  Thanks the more I look at him the more I think he's buckskin :)

I believe the baby is frame and frame IS the gene that causes LWO.  He most likely got it from his dam.   Frame can hide in solid horses although it is rare for it to do so it does happen.

Smokey brown is one of my all time favorite colors, for what it is worth.

 

Tovero is a pretty outdated term in the world of genetics because it only indicates tobiano and some other white causing gene, but doesn't specify if that other white gene is splash, frame, sabino, dominant white, etc. Or many of those, so you are correct that overo doesn't always mean lethal white... It can be all those other genes too...however since the foal is frame it had to come from one parent or the other. As you said it is unlikely that it came from the sire, so that means it most likely came from your mare, so in fact she does carry frame which is lethal white.

Do you have any winter pics of your mare?  Often the cinamon brown soft points become more obvious.  I think she is black though.  Brown probably came from dad who is probably AAt.  Since bay is dominant to brown you can't see that he is carrying it.
