here is an example:
lets say you are crossing yy * Yy.. first separate the letters (they are called alleles by the way)
so for yy --> you have y and y
for Yy--> you have Y and y
For the first gene yy --> put each corresponding letter on top as shown in the picture.. so horizontally. Now do the same thing for Yy but this time vertically.
Then in the corresponding boxes combine the letters and there u have it

On the outside of the Punnett Square you put the genotype or two alleles of the parents.
A Punnett Square is a square divided into 4 equal smaller squares. It is used to show the possible genetic outcomes of two people mating. To learn how to make one, visit the related link.
In a Punnett square, a capital letter represents a dominant allele.

Like a Punnett square??? A Punnett square shows the combinations of recessive and Domminant traits. any help??
Possible offspring alleles
A Punnett square is commonly used to predict the genotype of offspring based on the genotypes of the parent organisms. By crossing the alleles of the parents, the Punnett square can help determine the possible genetic outcomes of their offspring.
