Question

In a plant, tallness is dominant over dwarfness and red flowers are incompletely dominant over white flowers, the hybrid being pink. How many offsprings will be of tall height with pink flowers from a cross involved two plants each of which is hybrid tall and has pink flowers?, 4 16, 6 16, 10 16, 2 16

Hybrid tall: Tt, pink flowers: Rr. Hence, the cross is between TtRr and TtRr. Among the offsprings, only the genotypes TTRr and TtRr are tall and have pink flowers. The proportion of TTRr is 2 16, whereas the proportion of TtRr is 4 16 which amounts to a total of 6 16.
