My wife and son quite happily discuss the article on "
Axolotls - Genetics and Colour" calling it "insightful" and "accessible". I however, having read the article several times, am not convinced I've completely grasped it yet. Please don't correct me if I'm wrong, but in a nutshell:
The chromosomes and DNA combine to produce proteins which break down the gametes allowing locus zygotes to undergo meiosis leading to phenotypes and genotypes which are largely homozygous unless they are heterozygous which would be down to the chromatophores or melanophores in a M/m, M/M, m/m combination and the eumelanin and carotenoids, lacking pteridines, giving us those xanthophores in an AX/ax, AX/AX, ax/ax arrangement without iridophores, purines or alleles in the dominant genes or the recessive genes, because A/a, A/A, a/a developmental mutant cell migration bypasses the neural crests without axanthic, riboflavins.
I'm not 100% sure if an albino mum + an albino dad = albino babies, or if a melanoid mum + a melanoid dad = melanoid babies or if indeed a leucistic mum + a leucistic dad = leucistic babies...because I think somewhere, the grand-parents have some say in the matter.
