My paint gelding is a BS paint. He is a big bay with a blaze and some roaning.
But my question is both of his parents were Overos... How come he is solid? Sorry if this is a dumb question, but it has been bothering me lately.
He does have a blue eye also.
First of all, toss out the word "overo". It really is an archaic word that has no relevance today when discussing genetics. It literally means "my horse has white, but I don't think it is tobiano, so I am going to lump it as overo and be done with it."
As for your horse, he does have some white, so he clearly inherited a white pattern from one or the other of his parents. See, the thing with white patterns is that sometimes, they express minimally. A blaze, a star, a tiny snip of white on one heel, there are all still caused by white patterns. They are just restricted to these tiny markings. So your horse got the pattern, and just didn't express it as much as his parents.
Assuming he is the horse in your avatar, I would say there is a good chance he has frame, which is causing the white blaze and possibly the blue eye.
No I know, I just didn't know that Overo was a term not being used so much any more. I still used it lol
A lot of people still use it. I was reading the Arizona Equine Connection the other day while my friend and I were waiting for the vet to come look at her horses (they were attacked by a mountain lion) and they had an article on pinto patterns (specifically tobiano) and they only differentiated sabino from the rest of the "overo" genes. Drove me up the friggin' wall!! Posted via Mobile Device
Just like Chiilaa said, even though he clearly inherited some pattern for white markings, they don't always express as something flashy.
Note: the following statements are purely hypothetical illustrated by random internet pictures. I'm not actually sure if the patterns of the sire and/or dam could produce a maximum white foal.
So, if this horse
Was bred to this horse
They might have one foal that looked like this
And another foal that looked like this
Or maybe even a foal that looked like this
That's why I've never understood stud ads that say "guaranteed color on foals". They can't guarantee that. They can guarantee that the foal will inherit a color gene, they can't guarantee how much expression that gene will have.
