Hey all, new here and still getting used to the forums. I have a question in regards to breeding MBKs and how their genetics play out with other colubrid morphs, dominant vs recessive genes, etc - the closest I’ve found is a site saying that a MBK x Corn = Black JungleCorn.
Specifically, I’m interested in how the all-black genes of MBKs would play out with something all white such as a Snow / Leucistic. Unfortunately the MM genetic calculator fails to have MBKs listed at all.
I would appreciate any info there is to be had.
Thanks!

Are you meaning if you cross an MBK with a Snow/Leucistic non-MBK? The answer is the Snow/Leucistic wouldn’t do anything in a single generation, as not only are those genes recessive, but likely incompatible between species. You’d just get the blend of Kingsnake + wild type of whichever other colubrid species you breed it with.

Aha! That makes sense, thank you!

You’re welcome! Obviously it’s a bit more complex overall, and there are things like allelic genes that may exist, but the most basic answer is that.

Jess covered the first key point but completing the answer, a leucistic (hybrid) MBK would still be an all-white animal. Leucism, as a phenotype, is dominant to all other pigmentations

Thank you very much @t_h_wyman for using your knowledge to help complete my lack! I’ll note this little tidbit down.
