Mendel found no dominance in snapdragons with respect to red and white flower color. When pure red (RR)and pure white (rr)parents are crossed, the resulting Rr combination (one of each Gene)produces second generation offspring with pink flowers. Suppose one of these second Generation pinks is crossed with a pure white. What is the probability that the resulting Snapdragon will have pink flowers?
A)0.25
B)0
C)0.75
D)0.5

Quizplus · Accepted Answer

The cross between a pink snapdragon (Rr) and a pure white snapdragon (rr) will result in offspring with a 1:1 ratio of pink (Rr) to white (rr) flowers. Therefore, the probability of getting a pink snapdragon is 0.5 or 50%.
