Mind-Blowing Facts About Genetics That Doctors Wish We All Knew

Chimerism isn’t just about different DNA in different parts of the body—it can also mean that one part of you is male and another is female. This might sound surprising, but it’s true. Sometimes, people can have cells with different genetic information without even knowing it until they get genetic tests done.

For example, your left shoulder might have male cells while your right shoulder has female cells. This condition can remain hidden for a long time, only coming to light when tests are carried out. It reminds us of our bodies’ incredible complexity and the surprising ways genetics can shape our identities.
