Answer 1

0%

Step-by-step explanation:

Without having to do a punnett square, you need two lowercase letters to have a recessive trait, from the available parents, you only have one lowercase letter for both traits, so you won't be able to have any recessive traits so you will have a 0% chance of having a dwarf plant with yellow plants.
