what is Punnet Square(Checkerboard) --- Prediction of Genotype and Phenotype

 The genotype and phenotype resulting from the recombination of gametes during fertilization are more visualized by constructing a Punnet Square. All possible gametes are assigned to a column or a row, with the vertical columns representing those of the male parent and horizontal row. Those of the female parent. After entering the gametes in the row and columns, the new generation is predicted by combining the male and female gametic information for each combination and entering the resulting genotypes in the boxes. This process represent all possible random fertilization events.

The genotypes and phenotypes of all potential offspring are ascertained by reading the entries in the boxes. Punnet square is also known as Checkerboard.
