Apunnet square predicts a 9: 3: 3: 1 ratio for phenotypes. explain what that ratio means..

The punnet square gives the frequency with which each phenotype is observed. In this case, the possible outcomes are 9 + 3 + 3 + 1 = 16,  9 members will have one phenotype, three members will have a second phenotype, three members will have a third phenotype and 1 individual will have a fourth phenotype.
