In any case, they have more than one set of DNA in the same body, so they containthe code to make two separate organisms. Basically the first step would be that two eggs get fertilized by different men's sperm. This is called fusion chimerism, or tetragametic chimerism. But many people who have the condition will never take a paternity test for their children, or find out through other means. Tylor was born with large skin coloration in her left torso, which her family and doctors believed to be a huge birthmark. The fate of these cells in offspring has not been adequately described.

Recent studies have shown that brain development in response to prenatal stress may change by epigenetic inheritance for several generations, independent of genetic predisposition. Experts aren't sure how many. Modeling this risk factor in animals, when influenza infection is induced in pregnant rodents during pregnancy, their offspring Show several behavioral and histological abnormalities consistent with human mental illness [7]. in an experiment aimed at curing volumetric muscle loss (VML), which often causes lifelong disability due to muscle function loss or limb loss. Their split coloration is the result of two different embryos fusing together. Fertility treatments are much more likely to lead to multiple births, and so are in turn far more likely to produce more people with chimerism.
