Mendel Found No Dominance in Snapdragons with Respect to Red

question 122

Multiple Choice

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 red flowers?

• A)0.25
• B)1
• C)0.75
