If a plant has no Casparian strips, it will not be able to
control the amount of water it absorbs and solutes. Casparian strips regulate
the amount of water that gets to the xylem. Without it, a plant won’t be able
to control the amount of water going to the xylem.

The only possible phenotype is large ears.
This is because using a punnet square reveals that each option has a dominant allele of large ears, leaving no room for the recessive trait of small ears.
Hope this helps!
If there's options, I assume mutation?
