You know how there chimera salamanders and stuff? Well what if a axolotl had a baby with a tiger salamander and it was a chimera and only one half of it morphed? what would happen to the sal?

If the hormones are being produced to induce morphing, the whole animal would morph. The reason axolotls don't undergo metamorphosis is because they don't produce sufficient quantities of the necessary hormones.

I can't imagine an animal like that would be very hardy.

So no chance of a half baked sal?

No, both halfs would be controlled by the same hormonal system.

Frogman, a chimera is an inidividual that is formed by the fussion of two zygotes, which means itīs made of two separate and distinctive celular lines. In axolotls it can follow a striking sagital symmetry, where one half is, letīs say leucistic, and the other half, wild type. In humans itīs far more convoluted.

the only way I can imagine, in theory, a chimera only half-morphed is if one of the two genomes has a genetic receptor defect that would prevent cells from binding the hormone for metamorphosis.

In theory, anyways. Just a nerdy idea...

for kicks and giggles, here a couple links to Dunbar's Gold, an extremely rare chimera quarter horse stallion. He has a brindle coat as a result of chimerism, which is a very rare color in horses. Crazily, one of his genomes is female - obviously not the one forming his 'nads, because he's a successful breeding stallion

without genetic testing, they would never have known. Which means, any one of us could be a chimera! In fact, some have hypothesized that chimerism isn't as rare as generally believed, because in many cases it would require genetic testing to be uncovered.
