What Is a Gene?

Genes are the instructions for life as we know it. They affect your development before you're even born and play a role in everything from your appearance to your personality.  Genes contain information about your heritage and your risk for certain diseases.  Understanding your genes is part of understanding yourself, and you can use information about genetics to make decisions in your daily life.
