Krimsky and Simoncelli also stated that potentially every human being could exhibit some trait of chimerism, which they claim may impact the way that forensic scientists collect and utilize DNA in crime scene investigations. That is due to the fact that Fairchild and Keegan exhibit two DNA lines only in very specific areas of their bodies, and only at a microscopic level. But Fairchild and Keegan, as human chimeras, show that DNA may not always accurately identify an individual or biological relationships. PubMed We would also like to thank Dr Akiko Helena Popiel for valuable comments, Tatsuro Ikeda for drawing of the Figures. Robinson-Gissette spoke in their interview about having tetragametic chimerism.

As a consequence, instead of having cells with identical DNA throughout their body, a chimera has different DNA present in different parts of their body so that the DNA in their blood, for example, may not be the same as the DNA in their saliva. In 2002, after applying for government assistance in the state of Washington, Lydia Fairchild was told that her two children were not a genetic match with her and that therefore, biologically, she could not be their mother. They sometimes create mythical creatures and they make the world a more interesting place. The B-allele frequency of the SNP array showed a mixture of three and five allele combinations, which excluded mosaicism but not chimerism, and suggested the fusion of two embryos or a shared parental haplotype between the two parental cells.
