So I am obsessed with splash. Slightly irratated after having to tell a BREEDER that only frames have lethal white.

Sorry for slight vent. Budweiser clydes Splash? Or just Sabino? Both? Some splash some sabino?

[Lou3]

clydesdales only carry sabino, they do not carry other pinto genes - or if they do they are NOT purebreds.

(Oh and lethal white can occur with other patterns not just frame, even in tobianos, its just not very common)

Lethal white is not only carried by frames. It can be carried by all overos, quarter horses and sometimes a tobiano.

I believe some folks think that Splash DOES exist in the Clydes, in some form.

Lethal white can occur in conjunction with other patterns, but not DUE to any pattern/gene other than the Frame. Well, actually, it's the other way around - the LWO gene is what causes the expression of the Frame pattern (the expression can be very loud, very minimal, or non-existent, all controlled by other factors). LWO doesn't cause Tobi, or Sabino, or Splash. LWO = Frame, and Frame = LWO, nothing else.

The issue is that another pattern can totally hide the would-be expression of the Frame (ie a max white Sabino, an extensively white Tobi, etc), or the Frame can be non-expressed and the horse appear to be only Tobi, even minimally. But that Tobi isn't JUST Tobi, he's also Frame, just not visibly expressed as such.

Actually, it's technically the other way around - Frame is only carried by LWO's See above Until proven otherwise, which so far has not been done, despite several attempts, Frame and LWO go hand-in-hand, always, and exclusively.

It can be carried by all overos, quarter horses and sometimes a tobiano.

See above also for the Tobiano explanation. Several breeds carry Frame, including TBs. Frame is not associated with Splash, therefor it cannot be carried by "all overos"

[Huntpaints]

WHich overos cant carry it? I have owned splash, sabino, frame, qh , and have all been tested and carry it.

Mo, any of the patterns can carry it IF they carry the "frame pattern " aka lethal gene. It may not be visible on the horse that tests positive, but it's highly possible.

I've known homozygous tobis that carried it, solids that carried it, Qh that carried.

[Huntpaints]

I agree, the previous poster stated that not all overos can carry the gene, and was asking which she was referring to. That is why I test everything, then I know what to breed or not to breed to.

The ONLY pattern associated with LWO is Frame, period. But, since, as I explained above, Frame doesn't have to express (accphotography started a thread on this, showing an absolutely solid horse who is LWO positive), and since any other pattern can mask the Frame pattern if it is expressed, the visual of a horse is never any guarantee. Even a Sabino can look like a Frame at first glance. If another pattern is LWO positive, then the horse is ALSO a Frame, whether it's expressed or not.

You cannot tell what overo genes are carried by the pattern expressed. The only way to know is to test the horse. If the horse tested positive for LWO then it has the frame gene. You cannot tell visually or how the horse is listed by the registry.
