Punnett Square

 

a graphic method proposed by the British geneticist R. Punnett for visually representing the combination of different types of sexual cells, or gametes, during crossbreeding. Female gametes are arranged along one side of the square, and male gametes along an adjacent side. The genotypes formed from the combination of the gametes are inscribed within the grid. The use of the Punnett square facilitates the calculation of the possible combinations of different types of gametes.
