A mosaic is a type of chimera. But rather than half half of 2 different morphs, it looks like it’s marbled!
‘Mosaic is a result of two cell DNA forming into one. This seems very similar to the chimera morph, but it is completely different. While in a chimera the embryo splits in half, in a mosaic morph each cell displays phenotypes of both cells coming from both parents.
Mosaicism is not a natural development and you cannot breed such morph. It is a natural accident causing rare axolotl colours.’
