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 red. What is the probability that the resulting snapdragon
Will have white flowers?
A)0.25
B)0.75
C)0
D)0.5

The cross between a pink snapdragon (Rr) and a pure red snapdragon (RR) will result in offspring that are either red (RR) or pink (Rr), but none will be white (rr) because the white allele (r) from the pink parent is always paired with a red allele (R) from the pure red parent.
