Detailed explanation-1: -The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C.

Detailed explanation-2: -Definition. A pedigree, as related to genetics, is a chart that diagrams the inheritance of a trait or health condition through generations of a family.
