What proportion of the offspring would expect to be dwarf

In pea plants flower position, stem length, and seed shape are controlled by independently assorting genes. Each characteristic has the following mode of inheritance:

Character Dominant Recessive
Flower position Axial (A) Terminal (a)
Stem length Tall (T) Dwarf (t)
Seed shape Round (R) Wrinkled (r)

If a plant that is heterozygous for all three characteristics is allowed to self-fertilize, what proportion of the offspring would you expect to be dwarf with terminal flowers and round seeds? Use the probability method to solve this genetic problem.
