Without knowledge of her condition, Lydia was accused of fraud. How could this be possible? Lydia conceived both of her kids naturally, carried them to term, gave birth, and was being told she was not their mother. Her husband was confirmed as their biological father, but the test indicated she was not the mother. She was required to prove a biological relationship to the kids, so she submitted DNA samples for routine DNA relationship testing. At the time, she was pregnant with their third child. Lydia applied for child support for her two children after separating from her husband in 2002. Perhaps the most famous example of a human chimera is Lydia Fairchild. Hospitals are usually ill-equipped to identify and treat chimeric individuals. When the hospital staff discovered he has two different, incompatible blood types flowing through his veins, they asked if he had received a bone marrow transplant. One young chimeric father I know reported being sent to a hospital after a car accident. As you can imagine, this condition can lead to confusing results when the person seeks medical care or relationship testing! So a DNA test result would be entirely different depending on where the sample was originally from (blood, saliva, fingernail clippings or hair, etc). One genome is found in one region or organ(s), while the other genome can be predominant in other organs or tissues. Chimerism is a condition whereby a person has not one but two complete genomes (or sets of DNA) in their body. Although this monster never existed beyond our collective imagination, the health condition is quite real.

The term chimera is derived from a Greek mythological creature that was composed of a goat, a lion, and a snake. This might sound like science fiction, but this genetic condition is real and it silently impacts the lives of everyday people. The lab tests the alternate genome, which doesn’t match the DNA in his blood. At the scene of the crime, he only leaves traces of the alternate genome behind. OctoYou may have seen an episode of CSI where a man is exonerated from a crime he actually committed because he has two different genomes (sets of DNA).
