The more that I looked at DNA, the more I realized it was nature and nurture. It's how genes and your environment work together to produce the person you are.

Genes are like the story, and DNA is the language that the story is written in.

You learn a lot about a person when you work together.

It's often meaningless to talk about a genetic trait without also discussing the environment in which that trait appears. Sometimes, genes don't work at all until the environment awakens them.

Mutations can arise anywhere in the genome, in gene DNA and noncoding DNA alike. But mutations to genes have bigger consequences: They can disable proteins and kill a creature.

Genes work with probabilities; they don't work with certainties. So most things that you're looking at with these genetic tests, it's not like you're condemned to automatically get the disease or the syndrome. There's a lot of factors in play there.
