Dominant and Recessive Traits

Dominant traits are the traits that people see that you have. Recessive traits are the traits that you have but people cannot see. Some traits are dominant because they can cover up other traits. When someone has a recessive trait that is seen, that means that they inherited one recessive gene from each parent.

This Punnett square shows how a recessive trait can be passed from two parents that show the dominant trait. Remember: a recessive trait is seen only if a person has both the genes for it.
