What was the name given to those type of people it started with a "C"? and does the show come one again? Very Very intresting for everyone to watch.

Chimera
How does someone become a chimera? There are a number of ways this can happen:
First, it is possible to become a chimera if developing fraternal twin embryos fuse together to become one embryo. (Think of this is as the reverse of identical twins where a single embryo splits into two.) This happens very early on when the embryos are just unspecialized cells, so a healthy baby can still be made. Fraternal twins do not have the same DNA, so a mixture of two embryos will give a chimera.
Second, chimeras can arise when developing fraternal twins share a blood supply. This happens when the twins (who have different DNA) share a placenta and cells from their blood mix. The twins will be chimeras only in terms of their blood since other cells in the body are not affected by the blood supply.
Third, sometimes chimeras can happen through an error in the way cells divide in the developing embryo. (These people are technically called mosaics but the concept is similar.) Cells split into two to make more of themselves – something embryos need to do a lot of to grow into a baby. For this, cells need to double their DNA and divide it between the two new halves. Sometimes this goes wrong and some new cells end up with different DNA. If this happens early on, the tissues that come from these cells end up with a different genotype.
How common are chimeras? We don’t really know. We generally only find out about chimeras when their DNA is analyzed. It sure makes crime solving difficult, but it can also complicate finding organ donors.

Try a Netflix search-it was called "I am my own twin" I think and the other answerer had the correct name for the circumstance of it-

Wow. I didn't know this was real. It was on an episode of All My Children. I thought it was something the writers made up.

I saw it but don't remember. Check out the website and see when they may schedule it again.
