Splashed White in gypsies
This article erroneously claims:
"In the Gypsy horse, this pattern is called "blagdon:" "a solid colour with white splashed up from underneath."[2]"
[2] http://www.vanners.org/wp-content/uploads/2010/02/Breed_Standard-021309.pdf
The reference makes no claim that blagdon is genetically Splashed White, and is merely describing the patterning. The description is general enough that on this evidence alone it's not possible to clarify exactly what blagdon refers to, and the usage of the phrase "splashed up" could be misleading. Note also that genetic traits such as Tobiano are consistently capitalised, while the phrase "splashed up" was not.
For your reference, a blagdon gypsy typically looks like this: http://www.gypsymvp.com/horses/sundance/sundance.html
Note the irregular edges of markings, and the belly spotting. Compare this to Splashed White, in which "the margins of the white markings are crisp, smooth, blocky, and well-defined" and which usually looks like the horse has "been dipped, feet-first, into white paint". This bears no resemblance to blagdon.
In other breeds, blagdon is called sabino, and is genetically Sabino 2.

I have been unable to find any evidence of a gypsy with clear Splashed White traits, or which has tested positive to SW1, SW2 or SW3.
If you want to claim gypsies have Splashed White, you cannot do it based on the quoted reference. In the absence of any supporting evidence, I recommend removing the above claim from this article.

- At this point, I dispute that this is an "error," but I think it's OK to move that bit from the lede and put it in the body text. (I think it was someone working on the Gypsy horsse article who put it there in the first place). Not all spotting genes have been defined. However to the best of my knowledge (provide a source if you disagree) there is yet to be a "sabino 2" gene identified - there are undoubtably multiple spotting genes yet to be identified, and a lot of what we used to call "Sabino" is now being identified as splash or even dominant white (for which there are now 20 alleles identified). Your example is what I'd personally call a sabino, akin to that color in the Clydesdale horse, but I must admit that it does fit some descriptions of SW-1 ("extremely large blaze, extended white markings in legs, variable white spotting in belly."). So, unless someone has done genetic testing to rule it in or out, these horses may very well be SW-1. According to UC Davis, the SW-1 may exist in more breeds than have been mapped to date. Some "sabino" coloring is called "splash" at times, particularly in Europe. I also must note that the SW-1 has extraordinary variability: see here. Montanabw(talk) 02:46, 28 November 2014 (UTC)
- While you are right that SW1 can potentially hide or be mistaken for other things, there is not yet any evidence to support the hypothesis that SW1 is present in the gypsy breed, or that it goes by the name of blagdon if it does occur, but this article states it as fact. It seems to me that this has just arisen from someone misunderstanding the source material, rather than from clear evidence such as genetic tests or studies.
- This statement appears to constitute original research, as it "reaches or implies a conclusion not clearly stated by the sources themselves."
- Without any supporting evidence for this statement, it needs to be omitted until such evidence is found.
