From Vinny Lynch's morphs page:
Recently, vanishing pattern and patternless sinaloans and nelsons have begun to appear with regularity, although their story is more complicated then the albino. There may be as many as three different lines of reduced pattern/patternless sinaloans in addition to a line of patternless nelsons (which also happens to be albino); to complicate matters even further there appears to be both recessive and polygenic inheritance at work in different lines.
The first reduced pattern sinaloans were produced by Robert Seib, and appear to be the result of multiple genes with a "super" form having a severely reduced pattern that may be completely absent.
An unrelated line of normal appearing sinaloans at VMS herp threw a patternless animal in 2003, although yet to be proven this trait is likely to be recessive (Ed. it has been proven recessive, check out VMSherp for pics).
The third line of patternless sinaloans is at VPI, these animals have subtle but distinguishing differences from the previous lines suggesting there is a different mutation at work.
Thus far, the only patternless nelsons, which also happens to be albino, has been produced by Rick Millspaugh. The patternless nelsons is remarkably similar to the VMS-line patternless sinaloan, suggesting the same mutation is responsible for the trait in both species.
