To determine the results, lets make a punnet square to check for the probabilities.

Ty Ty t y t y

TY TTYy TTYy TtYy TtYy

Ty TTyy TTyy Ttyy Ttyy

TY TTYy TTYy TtYy TtYy

Ty TTyy TTyy Ttyy Ttyy

4 out of 16 pea plants will have the probability of having the genotype TTYy. There will be a 25% chance that the offsprings will have the genotype TTYy.
