- Elaphe guttata guttata
Many people seem to think that the snow colouration is the result of a single recessive gene. It is really an anerythristic, amelanistic animal. In other words, it lacks the ability to produce black pigment and it lacks the ability to produce red pigment. Over the last few years we have seen the development of several different snow corns; Green spot snow corns, with greenish saddles; Rose snow corns, with pink saddles; Blizzard corns, with no markings; Striped corns; and now the xanthic, Butter corn. The specimen in the above photograph is heterozygous for striped.
