I have black hair and brown eyes. How can I have a baby with blonde hair and blue eyes?
Physical traits like specific hair and eye color can be either dominant or recessive. For example, your mother may have given you DNA that would result in blue eyes, but your father may have given you DNA that would result in brown eyes. Brown eyes are dominant over blue eyes, and therefore your eyes are brown. You still have the DNA for blue eyes that your mother gave you, and that is just as likely to be passed along to your child as the DNA for brown eyes that your father gave you. The same is true for hair color and other physical traits.
