The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. These tables can be used to examine the genotypical outcome probabilities of the offspring of a single trait (allele), or when crossing multiple traits from the parents.
Allow 1 credit for correctly completing the Punnett square as shown below. All four boxes must
be correct to receive this credit.
Example of a 1-credit response:
A AA AB
B AB BB
Note: The order of the letters in each box does not matter, for example, AB is the same as BA.
