Punnett Squares

Punnett squares are a tool used in genetics to predict the possible traits an offspring might inherit from its parents. Developed by Reginald Punnett, these diagrams help visualize how dominant and recessive alleles are passed down. Each square in the diagram represents a possible genetic combination that a...

A Punnett square is a powerful tool named after the scientist Reginald C. Punnett. It shows the possible genetic combinations from a genetic cross.

To create a Punnett square, we start by identifying each parent's genetic makeup or genotype. Then, draw a square divided into four smaller boxes and label each parent's alleles—a gene's diffe...
