The Mother Who Failed Her Maternity Test
Though it doesn't happen frequently, it is possible for a woman to fail a pregnancy test. And based on that, you might infer that the woman was pretending to be a mother. In 2002, Lydia Fairchild had to put up with that. She had sought for social assistance, which required documentation proving each family member's relationship to the other. But her DNA test revealed that her children were not hers. She was falsely charged, and she nearly lost her kids. But she was aware that they belonged to her.
50% of a child's DNA comes from their mother and 50% from their father. In a DNA test, we use PCR to extract and amplify DNA from the supplied DNA samples (polymerase chain reaction). We can map the mother and child's DNA profiles thanks to PCR. Each test subject's individual profile consists of a total of 21 genetic markers. A genetic marker is a gene or DNA sequence that may be used to identify people and has a known location on a chromosome.
Fairchild turned out to be a genetic chimera. Two fertilized eggs by her mother most likely resulted in non-identical twins, but one of the eggs was digested, leaving Fairchild with a second set of genetic material. She was successful in establishing her case in court and was granted custody of her kids.
