In a certain plant, red fruit (R) is dominant over yellow fruit (r) and tallness (T) is dominant over shortness (t). If a plant with RrTt genotype is crossed with a plant rrtt genotype, what will be the percentage of tall plants with red fruits in the progeny?

Question

Accepted Answer

50%. The plant with RrTt genotype can produce two types of gametes: RT and rt. The plant with rrtt genotype can only produce rt gametes. When crossed, the probability of getting RT is 50%, and the probability of getting tall plants (T) is also 50%. Therefore, the percentage of tall plants with red fruits in the progeny is 50%.
