    In the case where two diploid eight-cell-stage embryos are used to make a chimera, chimerism can be later found in the epiblastprimitive endoderm, and trophectoderm of the mouse blastocyst. The look female and have infantile external genitalia with underdeveloped internal sex organs, but are infertile. McK was a discovery, and her very existence produced a kind of existential angst. And if chimaeras and mosaics are more common than we realize, they will complicate future efforts to tailor drug treatments to people's individual genetic constitutions.

    These kinds of chimeras can be made through either aggregation of stem cells and the diploid embryo or injection of the stem cells into the diploid embryo. It is not known how common tetragametic chimerism is in the population since there are often no outward signs, especially where same sex embryos have fused a few might have visible pigmentation mosaicism. This form of modification can also be beneficial when it comes to organ transplants. Responses were published in March The charge against her was dismissed when it became clear that Lydia was a chimera, with the matching DNA being found in her cervical tissue.

    Chimeras may also show, under a certain spectrum of UV light, distinctive marks on the back resembling that of arrow points pointing downwards from the shoulders down to the lower back; this is one expression of pigment unevenness called Blaschko's lines. These kinds of chimeras can be made through either aggregation of stem cells and the diploid embryo or injection of the stem cells into the diploid embryo. Freemartins occur in other species, but less often. This is also very unusual as the dilution gene which gave him the blue grey colour should have converted all red portions into cream.

It has been recently discovered that marmosets can carry the reproductive cells of their fraternal twin siblings due to placental fusion during development.

Human Chimeras Human chimeras also occur. In many cats, these forms of mosaicism will never be noticed because they naturally have black somewhere in their coloration; when the black is quite unexpected and defies logic then mosaicism is assumed.
