2. A dihybrid cross with complete dominance in both genes involves one parent heterozygous for yellow peas, but homozygous recessive for wrinkled peas, crossed with a second parent heterozygous for both traits (yellow, round peas). What is the expected genotypic ratio in the F₁ generation? A. 1:2:1:2:4:2:1:2:1 B. 3:1:3:1:3:1:3:1 C. 1:2:1:1:2:1 D. 9:3:3:1 E. 1:1:1:1 3. What is the expected F₁ phenotypic ratio (from the above problem)? A. 9:3:3:1 B. 3:1:3:1 C. 1:1:1:1 D. 3:1 E: 1:1
