This has been an interesting read. I LOVE sabino’s and actively searched for WB stallions that could be sabino. I know that’s not the best way to choose a stallion, I had other criteria as well ;).
The 2 that suited my mares the best:
Landkoenig & Donnerweiss GGF
both stallions are homozygous for black points.
This thread should generate a list of WB sabino stallions, could be fun to see how many are out there. 
Dominant White Hanoverians
As some of you already know, I have a pure white Hanoverian mare. She is eeAA but has no colour on her at all. She is almost certainly DW (has been tested negative for SB1) and is soon to be tested for this just to be sure.
I was wondering if anyone knows of any other DW registered Hanoverians out there?

Tobiano is linked to Extension - they go as a pair. Most of the time it’s linked to e. Sometimes, such as in the Samber line, it’s linked to E.
When it’s linked to e, then the color of the Tobiano is very similar to the color the horse would be without Tobi involved. The T will go with the e 93% of the time, but whether the horse is red-based or black-based will depend on the other parent. That’s why there will be a pretty even mix, over a large enough population, of red- and black-based Tobis.
But when it’s linked to E, E and T will go together 93% of the time, so over a large enough population, only 7% of the Tobis will be red-based.
I am pretty sure Art Deco - an E/T horse - has no chestnut tobiano foals out of solid mares.[/QUOTE]
I will have to dispel that rumour :-). Please see www.kimberleefarms.com/sales.htm. Look for American Art under sold horses and you will see an Art Deco chestnut tobiano colt out of a solid mare. Guess he is one of the 7%!

I doubt any are registered DW, but there are indeed quite a few out there Most are not blatantly obviously, usually listed as Sabino or Splash.

Tons of Sabino WB stallions Many are also Splash and/or DW, though the latter can be really hard to say for sure when it’s present in a minimal manner. Look at socks/stockings - if they are jagged, and below the knees/hocks, chances are pretty good for Sabino. If they start coming jaggedly up the knees and over the front of the hocks, chances are good it’s DW doing that. Look at face white - if there’s a lot that looks like it should have gone over an eye, but didn’t, chances are really good that Splash put on most of the white, but Sabino kept it off the eye. Or, if it went over the eye, but there’s black “eyeliner” - Sabino kept it just barely off the eye
Excellent!

Tell me more - can you think of any names? Are there any white ones or very loud ones about?
Gosh offhand I don’t know - very few of them are obvious. I do remember last year or so there was a very wildly-colored yearling (2yo? youngster anyway) Westphalian stallion who was really cool. He wasn’t named at the time, so I can’t find him 
I’d have to just start looking at a bunch of them to pick out the more obvious ones
Thanks JB - if any spring to mind please let me know. There have been mutterings that my mare may be the ONLY registered DW Hanoverian. Obviously I would love this to be true!

I have a bay sabino mare with four white socks, a star and a snip, with white through her lower lip. Bred to Freestyle, homozygous black with little to no white, she produced a black colt with four white stockings and a belly spot. So, his homozygosity didn’t suppress her sabinoness. (Great word, no?):D[/QUOTE]
I have a chestnut Dutch WB who is getting more white along her belly and flank the older she gets. She also has a white splotch on her wither, belly and rump, as well as a black spot on her knee and rump. She has a tall stocking on one hind leg and a big star, wide stripe with a lot of white hairs stretching to beyond her eyes and well beyond her nasal bones, and large snip on her face. She was bred to Freestyle and produced an all black colt with just a teeny-tiny crescent star on his forehead.
I don’t know if my mare is sabino or not… I kinda think not but I’m no expert. But she has a very unique hind roan leg. Are roan markings heritable? If I breed her, should I be wary of chromy stallions so I don’t get a solid roan? Her sire is Paparrazo and her damsire is Wertheson (she looks just like him). Would love any thoughts on where that roaning came from…
Her hind left, above the sock: http://s1201.photobucket.com/albums/bb359/we4boats/?action=view¤t=K0Q_7858.jpg&
That’s a not uncommon presentation of a Sabino-wannabe marking
You won’t end up with a roan unless you breed to a roan Sabino can cause roanING, as in, white hairs scattered in the coat, usually minimal, very occasionally pretty obvious.
Because she has so much real white, you could get something very chromey if bred to a stallion who also tends to throw a lot of white.

There are quite a few around… but in this case whilst they may have hano rego, they are actually very much TB influenced.

There was a lovely max white born by frozen semen a few years ago… will try and remember who and where in Australia it was!
OK… if you scroll down to nearly the bottom of this page, there was another white foal born, again , out of a TB mare (Just noticed that it says sadly deceased.).The mare is probably DW… By the stallion Budweiser

facinating thread!
Im learning a lot here…and I think I will have our stallion tested at UCD(Its only 5 miles away)
He is a newly approved stallion with ISR/Oldenburg and has interesting color. He is a mahogany bay, small sock, lower lip white…but with an odd white or roaning hand shaped spot on his left shoulder.
He was born with it and at his initial inspection it was asked if it was an injury. Nope, came with it.
His dam has small socks with ermine spots, lower white lip, and she is a dark brown. She is a Pointmaker daughter, Ive noticed in his pics that he is similarly marked. My riding horse is another Pointmaker daughter, same white lower lip and a faint star.
Im really interested to see what his color genetics might be and will do the testing to find out.
Belambi - thanks for looking that up for me.
In my mare’s case the DW has not come from a TB. It is thought to be a new mutation on the KIT gene. It is possible that she may be the only registered DW Hanoverian. Of course a minimally marked DW foal would not have been registered as ‘white’ so I am trying to think a little laterally! My mare is to be registered as ‘white’ with the Hanoverian Verband.
Congrats!.. Thats really unique!.. Will let you know if I remember the others… there are a few warmbloods, but not necessarily hano.
For sure, there are many, many horses with DW markings that are not at all obvious, just chalked up to Sabino or maybe even Splash. It’s only the more maximally expressed horses who are more obviously DW, but even then, it’s common place for them to be called Sabino too.
And yes, there seem to be all sorts of new mutations of DW!

Also, I remember a few years ago when I was doing a lot of research into the original cream hanoverians(isobellas) I remember reading quite a lot about white foals (not creams ) being NOT uncommon back then, and they were taken to the royal stables. ( The crest of the House Of Hanover is a white horse coincidently!)… But remember that is about 150 years ago! I remember reading that they were stabled at Herrenhausen and were specifically for either the King or the Queen.
In reading the new issue of Warmbloods Today, I saw one of the DW stallions I can’t believe I forgot about, as he’s pretty darn obvious (well, to those who “see” DW, he’s just not maximally expressed and “white”):
See how that white comes up the front of his knees, and particularly how it streams up his left stifle area? Very typical DW
His sire, Escudo I, is obviously Splash, but could very well have DW hidden, just not really expressed. There’s a hint at it with the white on his RH coming up the front though. Sabino would more likely jag it up the back of the leg.
I don’t have pictures of his dam, but his damsire, Federalist, also has some upward jag on his front whites which may, or may not, be DW.
