Answer:
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.
