[QUOTE=FriesianX;4076503]
Last time I read up on “markings” there really wasn’t enough known about the genetics of markings - other than tobiano and overo and their derivatives. I’ve had plenty of solid (SOLID) black foals with pinto sire and homozygous black mares over the years. It is believed that black is a pattern masker - which often takes care of pinto.
There is also some discussion that recessive sabino is more likely to show up than plain ol’ face and leg markings. You might take a close look at the markings - a small star or evenly edged pastern mark is different than a keyhold blaze or ermine spots in a pastern sock.
In all reality, if you are breeding your Friesian mare, you have a strong chance of getting solid (SOLID) black, since Friesians have a strong pattern block bred into them (since the registries won’t register anything with more than a small white star).
However, again, there is no conclusive studies yet on plain old face and leg markings that I’ve seen, and the question does come up quite often. I think the chrome producing stallions tend to actually be splash or sabino. By the way, chestnuts seem to have a higher incidence of those characteristics, even in recessive form, so although you would get Black or Bay (bay is a form of black), you are much more likely to get what you want from a Homozygous black, and probably not to worry about small white markings.[/QUOTE]
Black tends to mask sabino overo markings…not necesarily other ones…and in WBs tobiano is linked to black/it’s REALLY hard to get a chestnut tobiano. (Not so with Paints…just WBs).
