Genetic chimeras: Genetically created animals that are part human. One example being pigs that have human blood in their bodies instead of pig blood. These part animal part humans are created for medical research and I just heard about their existence today on NPR.
and there's a new medical disovery of human chimera's where one person contains 2 completely different sets of DNA. It happens when 2 eggs fuse at a very early stage and develop into a single embryo.
2 women had both been told that their children could not possibly be their own as the DNA made it totally impossible. Further testing revealed different DNA in different parts of their bodies. One baby with the condition had clearly defined lines of colour change in his skin, where the DNA changes occurred - almost chequerboard.
