Someone with a serious genetic disorder, or a carrier of an allele for a genetic disorder, wants to know the possibility that he'll pass it on to his children. Punnett squares are grids that organize genetic information. What a punnett square does is that it tells you, given the genotypes of the parents, what alleles are likely to be expressed in the offspring. Study the drawings for the sake of understanding then memorize the logic behind every ratio. Punnett squares are helpful much of the time, even.

A punnett square is a tool used in mendelian inheritance to show the possible genotypes that are formed when a male and female gamate unite. Punnett squares like this also help us see certain patterns of inheritance.
What a punnett square does is that it tells you, given the genotypes of the parents, what alleles are likely to be expressed in the offspring. In this lab, you will learn about and apply examples for 3 different patterns of human inheritance of traits. It is used to predict the possible offspring from a cross, or mating between two parents. In our example, we had a 1:2:1 genotypic ratio for homozygous dominant, heterozygous dominant, and homozygous recessive, respectively. Punnett squares like this also help us see certain patterns of inheritance.
