Aztec Mutation in Boas

The Aztec mutation was discovered in a school classroom and the genetics are still being explored. The mutation results in the saddles of the boa to fuse to form blocks which connext laterally running down the sides of the animal. Chromatophores are specialized pigmentation cells found in the dermis and epidermis of snakes.

The combination of pigments expressed by melanophores (black pigments), xanthophores (yellow pigments), erythrophores (red pigments), and leucophores (white pigments), gives snakes their coloration. It appears that Aztec boas have an increased number of all of these pigmentations, resulting in an increase in grey, yellow, red, and pink pigmentation.

This mutation is not well understood but it is either dominant or incomplete dominant. The homologous form of the mutation is expressed when the boa has two homologous alleles of the mutated gene, this is referred to as the “super” form. Homozygous Aztec boas have poor locomotive function and are generally weak. The heterozygous Aztec carries one mutated allele and one normal allele.

    Wow 2019 the morph out there for quite a while and so much misinformation.
    Bob and andrew pots (florida usa) bought a snake that was in a tank in a skool ,the bought it from the teacher.
    Bred it at their store and got the first axtecs.
    They than repeatet to see if it could reproduce and got a nother litter with aztecs.
    Than they bred an aztec to a normal and produced half a litter visual aztecs proven they were dominant.
    Than they bred aztec to aztec and got aztec and super aztec proven then incomplete dominant.
    These super aztect however suffer from neurological disorder making them woble.
    This can be becouse of them being close related.
    There are supers that reproduced resulting in full liters of aztecs.
    2019 in Belgium 3 super aztecs were born bred out of heavely outcrossed aztec ‘s produced by Walter Berg 2 of these show no sighns of a woble ,time wil tell how healthy these are but after 6 months they stil thrive.

      Hello Walter!

      Thank you for the information, I have been meaning to update the morph pages for a while but I guess time has gotten away from me. If there is any more information you could provide I would appreciate it.

      Thank you,
