Sabino often mimics the skunk
Sabino often mimics the skunk tail and ticking that many people associate with rabicano.
My suspicion is that when sabino and rabicano are paired, sabino amplifies and intensifies the rabicano patterning. That is how the two seem to behave in Arabians, in those cases where you have animals that breed as if they have two separate patterns.
In most cases though, the traits don't segregate. If as many horses were carrying both sabino and rabicano as people think, we should see horses producing both combinations and the two patterns separately.
There is also more than one kind of white ticking, which is why in the latest Sponenberg book the term rabicano was dropped in favor of "white ticking".
Rabicano (and sabino and splash) fall into the category of things that we really just don't known enough about to say that it is "definitely" there. We don't really know the boundaries of the expression of many of these patterns. We can make guesses, of course, but until there are tests - or at the very least a commitment to do the in-depth research on pedigrees and families - there is a limit to how reliable our answers will all prove to be in the long run.

Can you give some examples of families where the traits don't segregate?
Most of the Crabbet lines are
Most of the Crabbet lines are this way. You see flank roaning and even skunk tails, but you do not see pure rabicanos (that is, a horse with banded roaning, a skunk tail and little or no white on the legs) in most of those strains.
Crabbet horses were often crossed out to lines without a lot of white in the 1980s, and one would expect to see a certain number of rabicano-only horses from those crosses. Yet the rabiano-only horses remained confined within a pretty limited number of (non-Crabbet) bloodlines.
Arabians are one of the best tests because we know that specific kind of white ticking (the kind not related to markings) is there. There are other breeds where the sabinos are roaned in this fashion (flanks and tailhead), but where the classic rabicano look cannot be found. Maybe it is there in low numbers, but if you have all those sabinos that are supposedly also carrying that separate gene, it should not be so hard to find an example, especially when solids are present to give you the not-sabino option.
I'm not saying that there aren't rabicano-sabino horses out there. I suspect that is what this guy is:

and his sire, too:

(he has suppressors going on, I suspect)
I just think that sabino can and does mimic a lot of the aspects of rabicano.
I suspect the horses linked above are carrying both patterns, but then they are bred the right way to carry both patterns. Without knowing the family a horse comes from, it can be hard to know for sure what is causing the color. (And of course, even then it's still often just guessing!)
But that is the way you prove the existence of two patterning genes in one animal. Barring linkage, the two patterns should segregate. That is why I am skeptical of many horses being labeled as splash simply because they have blue eyes. Other patterns mimic that trait, so their presence does not prove that splash is there. (Otherwise you have circular logic: it is splash because the eyes are blue, and the eyes are blue because it is splash.) What proves splash is the presence of the pattern in its pure form. The same is true for rabicano. Find it in its pure form, or in a family where the pure form is known to occur, and you are closer to proving it there.
I'll look up his pedigree.
I'll look up his pedigree. Gimme a few minutes. :)
[Edit]: ok, got it. I added him to AllBreed. Here ya go: http://www.allbreedpedigree.com/zippos+…
He was born in 2005 and is still registered as a stallion (if he hasn't been gelded..) His sire looks like he was registered grey (by a blue roan and out of a grey). Dam was registered chestnut out of two sorrels.
Not sure if this actual report with work if you guys aren't logged in... Just shows all the colors.
That is definitely rabicano.
That is definitely rabicano. Those leg markings are really cool. I wonder if frame is a possibility? I can't look up his pedigree either as I've let my AQHA membership expire.
