What is an allele?
A type of gene that controls a particular trait. It can be dominant or recessive.
What do Punnet Squares help to show?

What is a trait?
A physical characteristic
If the squares of a Punnet Square show: Dominant-Dominant, Dominant-Recessive, Dominant-Recessive, and Recessive Recessive, what would both of the parents have to be?
