The Mysteries Of Science
The term Chimerism is derived from a mythological Greek monster, Chimera. Chimera, a combination of a lion, a goat, and a serpent, who was a symbol of ill fortune. For Lydia and Karen, chimerism didn’t affect their outer appearance but was only detectable by their genetic testing.
However, chimera formed by male and female twins can result in a hermaphrodite. When the twins are of the same-sex, Chimera can result in different color patches or different eye colors. For animals, this condition takes a long jump.
