Correct option is B
The correct answer is: (B) 9:3:3:1
Explanation:
A Dihybrid Cross involves two different traits being inherited together. In Mendel’s experiment, he crossed pea plants that differed in two traits (e.g., seed shape and seed color). The F₂ generation resulted in a 9:3:3:1 ratio, following Mendel’s Law of Independent Assortment, which states that genes for different traits are inherited independently of each other.
Information Booster:
- Example of Dihybrid Cross (Mendel’s Pea Plants):
- Round Yellow (RRYY) × Wrinkled Green (rryy)
- F1 Generation: All Round Yellow (RrYy)
- F2 Generation Phenotypic Ratio:
- 9 Round Yellow
- 3 Round Green
- 3 Wrinkled Yellow
- 1 Wrinkled Green
Final Ratio:9:3:3:1
