A diagram that is used to predict an outcome 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.

Heterozygous crossed with a Heterozygous:
Red = Dominant When you cross a heterozygous red-white flower with a heterozygous red-white flower, you will end up with the offspring of 75% red flowers and 25% white flowers. Genotype = (50% = Rr) / (25% = RR) / (25% = rr) Phenotype = (75% = Red flowers) / (25% = White flowers) |
