Correct answer: D. F2
- A. P1
- B. F1
- C. F3
- D. F2
Explanation
A clear-cut 9:3:3:1 phenotypic ratio was found in F2. The appearance of these new recombinant phenotypes of F2 indicated that some sort of shuffling of alleles had occurred during gamete formation. Mendel inferred the mechanism of this shuffling as an independent assortment of alleles into gametes.
