Your genes are instruction codes for your body—telling cells what to do. These instruction codes do everything from telling your body when to start puberty to determining the shape of your nose.

Everyone’s special set of genes comes from their parents. And, genes are an important part of what makes you unique. Unless you have an identical twin, there is not another person on the planet with a set of genes exactly like yours.

Genes affect how you look, act, and can even affect your health. So, some of the stuff you really like about yourself (and, some of the stuff you don’t) just might be in your genes. Wanna know more?
