An example of a punnet square is if you have the heterozygous Bb genotype. The punnet square would have a big B and a little B at the top and on the side. The first square would be BB, the second one would be Bb, the third would be Bb, and the fourth would be bb. the possibility that the child has the bb genotype is 1/4.
A punnet square is used to work of genotypic and phenotypic ratios for different crosses of animals. Therefore in a punnet square you will find the genotypes of the offspring that resulted from the cross (mating).
Take the phenotypes of the two parents and have them above and next to a box:
(say that the mother is AA and the father is Aa)
....A A
A AA AA
a Aa Aa
Genotypic ratio: 2 homozygous dominant: 2 heterozygous: 0 homozygous recessive
Treat it like a multiplication table. Take the allele from the top and the allele from the side to get two alleles in each box. (If the dominant allele is present, have it be first)
Punnet squares are used to predict the allele of the offspring.
Tool used to predict results in Mendelian genetics; shows all the ways in which alleles can combine
you would need to have something else to cross it with to make it a punnet square.

Punnet squares show all possible allele combinations resulting from a genetic cross
Aa x Aa
It is called a Punnett square. It's used to determine the probability that offspring will have a particular genotype (set of genes).

A banana is a good example of a punnet square since it has absolutely nothing to do with a punnet square.
