The various pinto genes are not all linked to the same gene. Like I said before, SB1, Tobiano, & Dominant White (a LOT of which are mis-identified as Sabinos) are ALL linked to the KIT gene, along with Roan.
As of right now, Splash White is considered a separate gene, as is OLW (Frame) & Rabicano.
There is the "White Factor" that determines how expressed a horse's white is, which might be what you're talking about?
