:there are strains of snake sometimes sold as "albino blairs" which are hybrids between alterna and ruthveni. some of these snakes contain upwards of 75% alterna genes, but the albino gene came to them from another species.
:there are anerythristic alterna (both black gaps and 277) and hypomelanistic alterna (black gap). no one has seen an adult hypo as of yet (they were first produced 2 years ago).
To bad no true albino gray bandeds imagine they would look very nice would think will be not long in the future
