Question

A Snapdragon plant bearing pink-colored flowers is crossed with a Snapdragon plant bearing white-colored flowers. Their F1 progeny will show:

• A. 25\% Red : 50\% Pink : 25\% White
• B. 50\% Red : 50\% White
• C. 50\% Pink : 50\% White
• D. 25\% Pink : 50\% Red : 25\% White

Hint:

Incomplete dominance results in a phenotype that is an intermediate of the parent phenotypes.

Answer 1

The Correct Option is C

- Snapdragon plants display incomplete dominance.
- A cross between a pink (Rr) plant and a white (rr) plant results in:
\[Rr \times rr \quad \rightarrow \quad 50\% Rr (\text{Pink}) + 50\% rr (\text{White})\]
