    Default "Chimera" Lab

    I had seen a posting on Facebook of a yellow Lab that had a black band around its midsection. Then, today, I saw this photo posted.

    The explanation given was that the animal was genetically two animals ... both black and yellow.

    One of the comments on the photo was:
    A chimera is not a mixed breed dog. It happens when two separate embryos fuse together very early on and become one animal (or human) with two distinct DNAs. It can't be duplicated or bred.
    A subsequent comment clarified that the chimera dog can be fertile, but will produce either black or yellow offspring, not another chimera.

    Another comment indicated that this fusing of embryos may occur more often than we know, but if both embryos were yellow (or black) we wouldn't know that the fusion had taken place.

    It looks like someone put some boot polish on that dog. Just saying.

    Here's an interesting article on a chimeric horse.

    Happens occasionally in people also. But who knows how often.

    Kinda cool looking. Think it might provide some pretty effective camo in brown grass or dry wheat.

    You're right! How do we breed for that?

    You just need to find someone who breeds labs and African Wild dogs and magically you will get the rare (and purebred) camo lab... But it's not a mix .... the colors were always there in the lab!

    Instead of focusing on what’s missing, learn to appreciate what’s already there.

    Mosiac is another term used for it and it does happen, sometimes just a black splotch on a yellow, sometimes much more dramatic. There have been several threads here on it, some interesting photos, pretty sure if it were able to be reproduced predictably, there'd have been plenty on that bandwagon by now, lol. I've had one yellow pup with a tiny black mark on her head, kept thinking it was dirt to wipe off, poor thing. Another yellow with an oddly shaded patch on its side. I've seen a few mismarks from "reputable" breeders and yes, they were "WTH is THIS" when pup came out.

    Kindof ironic.
    I have 3 friends who each have a puppy with a mosaic. All pups are in the Houston area and under 4 months. All from different breedings. I've only seen one mosaic pup in my life, and all of a sudden 3? Now 4?!?!?!

    Better jump on that, David, and forget the FC/AFC breedings! Way more $$ in the "unique and rare Labrador", even if you have to slip in a different breed here and there to spice the pot.
