The Correct Option is C
Solution and Explanation
- Snapdragon plants exhibit incomplete dominance.
- Crossing a pink (Rr) plant with a white (rr) plant gives:
\[ Rr \times rr \quad \rightarrow \quad 50\% Rr (\text{Pink}) + 50\% rr (\text{White}) \]
- Crossing a pink (Rr) plant with a white (rr) plant gives:
\[ Rr \times rr \quad \rightarrow \quad 50\% Rr (\text{Pink}) + 50\% rr (\text{White}) \]
