WebOct 4, 2024 · Punnett Square Definition. A Punnett square is a graphical representation of the possible genotypes of an offspring arising from a particular cross or breeding event. Creating a Punnett square requires knowledge of the genetic composition of the parents. The various possible combinations of their gametes are encapsulated in a tabular format. WebThese two trait crosses are called dihybrid crosses. While the monohybrid cross would yield 3:1 ratios of the phenotypes, the dihybrid crosses would yield 9:3:3:1 ratios of all the combinations of each phenotype.
