Figure 2 The Punnett square is used to determine the probabilities of the genotypes and phenotypes in the offspring of a genetic cross. From the Punnett square, the phenotype of each possible genotype can be determined. For  example, the offspring having  EE, Ee , and  Ee  will have free earlobes. Only the offspring with the

Unformatted text preview: genotype ee will have attached earlobes. Therefore, the ratio of phenotypes is three with free earlobes to one with attached earlobes (3:1). The ratio of genotypes is 1:2:1 (1 EE : 2 Ee : 1 ee )....
