    Re: Paradox genetics

    However, I'm almost convinced they're not the same. Take a look at these two snakes, both owned by Taylor Nicole Dean:

    This is Gemini, who is a chimera.


    From what I've seen, this is how chimeras tend to appear, with a visible distinction between the 2 sets of genetics.

    On the other hand, this is Frank:


    Frank is more what is expected of a paradox, with splotching and banding of pigment visible.

    I have also noticed and agree that paradoxing seems much more common on morphs that minimize pigmentation, so it appears that these are patches where the pigment actually expresses. Given these, it appears that chimera and paradox are two different expressions. They visually express very differently.

    Still, I'm not sure that either of these can be bred for consistently.
    A chimera does NOT have the mashed together DNA of two different animals. A chimera has the CELLS of two different animals. The cells have not been mashed together enough to make two cells into one cell. The cells are only mashed together enough to make them grow into a single animal. A given cell has the DNA of either one or the other original fertilized egg. The DNA of that cell is identical to the DNA of the progenitor fertilized egg.

    Gemini is one cool snake! IMHO, both Gemini and Frank are paradoxes.

    A paradox is a chimera plus. A paradox has cell lines of two different animals plus the genetics of those two animals is different enough to identify that cell lines come from two different animals.

    I agree that paradoxing seems much more common on morphs that minimize pigmentation. But I think that is the result of the number of morphs that minimize pigmentation. I think that a paradox could occur if a pinstripe and a normal became a chimera.

    IMHO, there are a lot more chimeras out there than there are paradoxes. Many chimeras are never identified as chimeras because they are not paradoxes. And I also think that chimeras and paradoxes cannot be bred for consistently. Either in an expected percentage of babies or in number, size or distribution of markings.

    IMHO, a chimera could look normal or be a designer morph. It is likely to go unidentified as a chimera. A paradox is a chimera plus, with patches of different morphs or patches of a morph and normal. For example, if a male mojave was bred to a female lesser, a paradox could be a chimera where one fertilized egg had the genetics of a mojave/lesser BEL and the other had the genetics of a normal. A paradox would also result if one fertilized egg had the genetics of a mojave/lesser BEL and the other had the genetics of a mojave. A simple chimera would result from this mating if both fertilized eggs were normals, were mojaves, were lessers, or were mojave/lessers.
