Question

The Punnett square obtained by the dihybrid cross between two pea plants is shown in the table. Both plants have genotype RrYy. Based on the above data, a student has concluded that the phenotypic ratio of dihybrid crosses is 9:3:3:1. What comment would you make about the student's conclusion? A) She is correct. The ratio should be 9:3:3:1 B) She is incorrect. The ratio should be 9:4:2:1 C) She is incorrect. The ratio should be 4:4:4:4 D) She is incorrect. The ratio should be 9:5:1:1
