Allyson Walker · Answer 1

tall, oval, brown - 1

tall, oval, green - 2,

tall, round, green - 3

tall, round, brown - 4

Explanation:

dwarf (D) is dominant to tall (d), round (R) is dominant to oval (r), and green (G) is dominant to brown (g).

Pure-breeding tall, round, green plants were mated to pure-breeding dwarf, oval, brown plants.
