Fairchilds case was one of the first public accounts of chimerism and has been used as an example in subsequent discussions about the validity and reliability of DNA evidence in legal proceedings within the United States. Although there had been a witness for the birth and blood samples, the judge maintained his statement that Fairchild was being deceitful about the pregnancies in some way.

At first, the technical difficulties involved in finding these chimeras might have contributed to an underestimation, but given the large number of paternity tests and direct-to-consumer genetic tests regularly done, and the slow trickle of case reports in the scientific literature, its unlikely that vanishing twins are commonplace. And you are spot on! In response to that book, legal professor David H. Kaye published the article, Chimeric Criminals, in the Minnesota Journal of Law, Science, and Technology in 2013, in which he asserts the basis of Krimsky and Simoncellis book was completely unfounded.

To obtain This XX/XY chimera likely arose from a diploid maternal cell that was formed via endoduplication of the maternal genome just before fertilization, being fertilized with both X and Y sperm. The research team then received a grant from the National Institutes of Health to further study Keegan and her family, and found that Keegan had evidence of two distinct sets of DNA throughout her body. Clin Genet. Keegans family members, including her husband and two of her three sons, submitted DNA to see if they would be a match to donate a kidney to her. It divides into two, making copies of these chromosomes, and we think that every cell down the line ends up with the same genetic bundle. The XX/XY chimera is classified into some subtypes; tetragametic chimeras [2,3,4,5], parthenogenetic chimeras [5,6,7,8,9], androgenetic chimeras [5, 10, 11] and sesquizygotic twinning chimera [12].

Hum Mol Genet. Fairchild matched that pattern, having one set of DNA throughout most of the cells in her body, and another distinct set of DNA in her cervical tissue. An organism gets approximately half of its DNA from each of its parents gametes, or their sperm and egg cells, which carry DNA from parent to offspring.
