Dihybrid Crosses. A monohybrid cross involves only one trait. This is what we have been looking at so far. Ex. Only dimples, OR only tongue rolling ability.

Albinism is a disorder caused by a recessive allele. About 1 out of every 75 people carry the albino allele. Let’s say a mom & dad with normal pigmentation.
