Markings

I was just wondering if you have a minimally marked horse be it Tobiano, Sabino, Splash Overo, Appy (or all of the above :laugh1 ) and breed to for eg. a solid horse (so gene is coming from 1 parent) will they only ever throw minimally marked or is anything possible?? I have seen a foal from minimally marked mare and solid sire and the foal is quite loud in its markings. Also the stallion I had (solid) seems to have some sort of Sabino roaning but no "visual" markings yet last yrs colt has a splodge over his left eye and roaning. What I was wondering is if he can produce that could he ever throw leg white?? or would it just be the roaning and some of it has clustered so to speak. Hope that all makes sense :oops:

It all makes sense and anything is possible. That being said, minimal x minimal tends to throw minimal, maximal x maximal tends to throw maximal, and the minimal x maximal tend to throw medium. The effect can also be cumulative, so for instance if you're breeding similar white markings together, the resulting foals tend to have more and more white. Of course, that is true of any trait you breed for.

However Banner, Rowdy was a minimal Frame and is the reason there are some wildly marked outcrop frame minis out there from a seemingly solid stallion - he's the reason !...so sometimes they do come up trumps.

Rowdy only expressed on patterned mares, when bred to solids he tended to throw his own markings, and since no-one was testing then we have no way of knowing if they had Frame except when they have tested grand children.
It was John Gaza who started them (and me for that matter!!) off on the Pinto route, it had never occurred to me before that Rowdy was a Pinto, and I had no idea what Frame was in minimal, I had only seen it in Films of cowboys!!!
I am not sure John knew Rowdy was Frame, either....
A friend of mine has a minimal Tobiano, just two white socks behind, and he throws solid or minimal to solid mares and "ordinary" markings to loud mares, so it does seem to tone the pattern down.

That's why there are theories about "suppressor" genes at work, particularly in the minis, and also theories that patterns tend to express themselves more in the company of other patterns.
