Tiger Salamander & Axolotl (Ambystoma tigrinum, A. mavortium spp, etc.) The Tiger Salamanders and the Axolotl are so popular amongst hobbyists that they have been given their own topic. If you're particularly interested in the Axolotl, there is a large section of the forum devoted mainly to beginner Axolotl enthusiasts (not this topic).

OK for those interested in the myriad colours of axies and for my own edification I have prepared the attached table.

I have tried to make it more complete than other information that is freely available by trying to deal with the effects of various gene combinations. Don't know why but they never really seem to be discussed n any depth.

This is a work in progress but if anyone has any references that say different or knows better then I would love to hear what they have to say. Otherwise this is published for everyones reference. I hope it is found to be useful and apologise if I have made any mistakes. I welcome any and all corrections or discussions. Please email them to me at mikflounders@yahoo.co.uk.

Finally please note I am engineer not a biologist or geneticist but I find the subject as fascinating as axies themselves

Rep: smaxolotl is an unknown quantity at this point

This is fantastic!! I love a spreadsheet, so this helps me wrap my head around the topic. I'm glad you touch on all-black axolotls (do they have a special term?). I can't seem to find much information on what their actual genotype can be, but I'm very curious because My black axie has fathered a group that is now reaching maturity, and it would be helpful in considering future pairings. Anyway, thank you for your work on this!

I would note that it is untrue that axanthics die before sexual maturity.

Melanistic opposite of albino, happens in most species occasionally but is a dominate gene in Axolotls. true melanistics have no iridophores (shiny bits). if it has iridophores in the ring around the eye its a dark wild type.

honestly, i find it hard to believe you even tried googling what an all black axolotl is called. its not rare at all

Rep: curtpw has shown reliable knowledge
Default Re: AXOLOTL COLOURS VS GENOTYPES

You all might already know this, but the vast majority of animals listed in the spreadsheet are not Axolotls - they are Tiger Salamander + Axalotl hybrids and quite distinct from wild Axolotl populations. The so-called 'wild type' Axolotl is the only true Axolotl and even many (if not most) of these in the hobby have some Tiger Salamander genetics mixed in. Generation of the Axolotl lab model population through the hybridization of an albino Tiger Salamander with a Axolotl is well known on Caudata but some may not be aware that the specific genetics in play have been revealed over the last couple years: "Identification of Mutant Genes and Introgressed Tiger Salamander DNA in the Laboratory Axolotl, Ambystoma mexicanum": https://www.researchgate.net/publica...toma_mexicanum
