Step-by-step explanation:
Your hair, skin color, and eye color are In hareted by your parents. If you and your mom both have brown hair and your dad has Blonde that means you have Your moms gene for hair color. That also means your moms gene is a Domanent gene and your dads is prob. a Resesive gene. A Domanent gene over powers the Resesive.
Hope this helps :)
