Chimera Research Paper

Chimera according to the genome glossary is an organism which possesses cells or tissues with a different genotype. This can be caused due to mutated cells of the host organism or cells from a different organism or species. According to Greek mythology, the original "Chimera" (pronounced as kih-MEE-ra, and the adjective form "chimerical" pronounced as kih-MER-ih-cal) was a fire-breathing female monster with the head of a lion, the body of a goat and the hindquarters of a dragon. The terrifying Chimera may have merely been a product of a substandard family environment -- her father was the giant Typhon, her mother the half-serpent Echidna. Her siblings were the Cerebrus (the three-headed hound who eventually found work guarding the gates of Hell), Hydra (a nine-headed aquatic monster) and Orthrus (the runt of the litter, a prosaic two-headed dog). As per the mythology, Chimera pounced around making everyone wretched until one day a man
An operation was conducted when the child was 15 months old and the surgeons removed "an abnormal gonad and vas deferens." Pathology studies later exposed that these were actually an ovary with a fallopian tube attached. Studies revealed that the child's chromosomes had both female (XX) and male (XY) cell lines. This was explained to be that the child was an exceptional case of a true chimera which was a mixture of two embryos from separately fertilized eggs. The other likelihood was that two different sperm had unusually developed into a single mature egg before cell division had taken place. To distinguish between these possibilities, the researchers analyzed DNA near the centromeres of the child's chromosomes, which are involved in cell division.
