In a cross between true-breeding red-flowered (RR) and white-flowered (rr) snapdragons, what is the probability that a random F2 plant will have pink flowers?
A
50%
B
75%
C
25%
D
100%
Correct Answer
Option A
Detailed Explanation
In incomplete dominance, the F2 generation of a monohybrid cross between RR (red) and rr (white) results in a 1:2:1 ratio of red:pink:white. Thus, the probability of a pink flowered plant is 2/4 or 50%.
