Which statement is FALSE about Punnett squares?

• allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes
• determines the expected percentages of different genotypes in the offspring of two parents
• determines an offspring's actual genotype and phenotype outcome if two parents' genes are known
• can be used to determine a missing genotype based on the other genotypes involved in a cross.
