The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. [9] 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.
Punnett square for the agouti gene in mice, demonstrating a recessive lethal allele. [2] Lethal alleles were first discovered by Lucien Cuénot in 1905 while studying the inheritance of coat colour in mice. The agouti gene in mice is largely responsible for determining coat colour. The wild-type allele produces a blend of yellow and black ...
Punnett is probably best remembered today as the creator of the Punnett square, a tool still used by biologists to predict the probability of possible genotypes of offspring. His Mendelism (1905) is sometimes said to have been the first textbook on genetics; it was probably the first popular science book to introduce genetics to the public.
The predictions of the combinations of the gametes will be constructed on a Punnett square. [ citation needed ] In conducting a monohybrid cross, Mendel initiated the experiment with a pair of pea plants exhibiting contrasting traits, one being tall and the other dwarf.

English: Genetics diagram: Punnett square describing one of Mendel's crosses, between parents that are heterozygous for the purple/white color alleles.
English: A Punnett Square showing a Bb x bb cross for eye colour. Here, a heterozygous brown-eyed parent and a homozygous recessive blue-eyed parent produce 50% heterozygous brown-eyed offspring and 50% homozygous recessive blue-eyed offspring.
Punnett squares for each combination of parents' colour vision status giving probabilities of their offsprings' status, each cell having 25% probability in theory. Normal text denotes a person (or chromosome from a person) who has normal colour vision and no defective gene, italics: has normal colour vision and a defective gene, and bold: is ...
