Use the following information to answer the questions below.
Tallness (T) in snapdragons is dominant to dwarfness (t), while red (R) flower colour is dominant to white (r). The heterozygous condition results in pink (Rr) flower colour.
-If snapdragons are heterozygous for height as well as for flower colour, a mating between them will result in what ratio?

When two heterozygous snapdragons are crossed with each other, their possible gametes will be:
TR, Tr, tR, tr
The resulting offspring genotypes and phenotypes can be found using a Punnett square:
        |  T  t
-------|-------
R     | TR|Rt
r     | Tr|rt

The ratio of the offspring will then be:
6 (Tall, Red) : 3 (Tall, Pink) : 3 (Dwarf, Red) : 2 (Dwarf, Pink) : 1 (Tall, White) : 1 (Dwarf, White)

Therefore, the correct answer is B.
