What are chimeras?
June 27, 2016:
So what happens when a chimera has children? If let's say the ovaries or testes are made up of cells from both fraternal twins, is it possible that the sperm or eggs to be made up from both twins thus making the children chimera by default?

I heard it is possible for two twins to have different fathers. If these two twins, each with a different father, conjoin together, would the conjoined baby have two fathers? Is this even possible? If so, how would the genetics work for the conjoined baby?

If we make clone of a husband and a wife and then if the clones have a baby, will the baby of real parents and cloned parents be same as an identical twin!???

July 13, 2011:
DNA is passed from parent to child. When a woman carries a child that came from a donor egg (not of any blood or genetic relation to the woman), due to her blood being the same blood that pumps through the heart of the fetus inside her, does that fact change or alter the DNA of the fetus/child to show any blood or genetic relation to the woman who carried that fetus/child?
September 10, 2010: A friend who is a chemist told me about a recent discovery that fascinated me. Apparently, when a woman has a baby, not all of that baby's cells leave her body when the baby is born. He said fetal cells have been found living and growing in different sites in the mother's body. Is this true? Would that make her a mosaic? And what about babies that are miscarried--does the mom still carry cells from that baby in her body?
November 12, 2009: I recently read about a case where a person had both a pair of X chromosomes and an X and a Y chromosome. How does that happen?
April 23, 2009: How is a paternity test affected if the child is a chimera?

Your article on chimeras had me enthralled, but could you please explain more in depth how it is possible for 2 zygotes to fuse and actually what should have been two people ends up as one? Shouldn't this be impossible?
