Here are 10 extraordinary facts about genes.

Genes do a lot of wonderful stuff like making us who we are, but there are many other really cool things about them we don’t consider very often.

Here are 10 extraordinary facts about the molecular units.

Number 10. They can reveal some interesting historical tidbits. For example, testing showed that Genghis Kahn could have as many as 16 million male descendants walking around today. All of them have a common ancestor who lived around the conqueror’s time and stomping grounds. Plus, Kahn was just that kind of guy.

Number 9. Genes can make pigs glow. The effect comes as a result of injecting embryos with DNA gathered from jellyfish, waiting for them to become piglets, and then putting the animals under a black light.

Number 8. Fears may be genetic. Researchers from multiple US institutions including Emory University School of Medicine found that DNA in mice can be altered by traumatic events and then passed to subsequent generations.
