About

By definition, a “wild-type” has the dominant genes at all of these loci. In other words, a “wild type” has NO recessive features. [1]

Axolotls have 4 (or more) genes for coloration. Wild type means they are either homozygous for the wild coloration or heterozygous for one wild allele and one mutant allele (theoretically, all colors other than wild type originated from a mutation at some point).

D is dark, M is non-melanoid, A is non-albino, and AX is non-axanthic. The D gene makes them dark obviously, with brown/black coloration. The M gene is associated with iridophores, which make them iridescent or shiny. The A gene is associated with true albinism, a lack of pigment, not just white bodies and pigmented eyes like a leucistic. The AX gene is associated with xanthophores, which has to do with yellow and red coloration.

A wild type axolotl is either homozygous or heterozygous for the dominant version of each of those 4 genes. D/D or D/d, M/M or M/m, A/A or A/a, and AX/AX or AX/ax. [2]

Axolotls have three different kinds of pigment cells or “chromatophores” that each produces a different color. Iridophore, Xanthophore and Melanophores. [3]

History

In science:
Maybe surprisingly, at first the axolotl was distributed across Europe without being tied to specific research questions, and amateurs engaged in acclimatization and aquarium movements played an important role for the rapid proliferation of the axolotl across the continent. But the aquarium also became an important part of the newly established laboratory, where more and more biological and medical research now took place. Early scientific interest focused on the anatomical peculiarities of the axolotl, its rare metamorphosis, and whether it was a larva or an adult. Later, axolotl data was used to argue both for (by August Weismann and others) and against (by e.g., Albert von K€olliker) Darwinism, and the axolotl even had a brief history as a laboratory animal used in a failed attempt to prove Lysenkoism in Jena, Germany. Nowadays, technical developments such as transgenic lines, and the very strong interest in stem cell and regeneration research has again catapulted the axolotl into becoming an important laboratory animal. [4]

These axolotls darken over time. This helps them to maintain camouflage underwater and protect them from predators. The shiny speckles all over the body help differentiate the wild type from the melanoid. [5]

Appearance

Head

This Axolotl usually has dark eyes with a shiny gold ring around the pupil and purple/gray gills. [6]

Body

Wild type axolotls are dark grayish green with black and olive mottling. They also have speckles of gold from the iridophores.

Depending on the individual, wild axolotls may be nearly black, gray, or a lighter yellow-green. This morph has purple gill filaments and dark eyes with golden irises. Their coloration allows them to blend into the muddy lakebeds near Mexico City.[7]

Belly

Normals have a pale belly.
