Note about the question:

I looked for the complete question but failed in finding the parental genotypes. So in my answer and explanation, I will include different scenarios of different crosses that might result in the given genotype options. You just need to look at the cross that corresponds to the one in your problem. I hope this helps.  

Answer:

  • Scenario 1)  TT   x   tt ----> F1) All tall, Tt
  • Scenario 2) TT  x   TT ----> F1) All tall, TT
  • Scenario 3) Tt   x    tt ---> F1) 50% Tall, 50% Short
  • Scenario 4) Tt   x   Tt ----> F1) 75% Tall, 25% Short
  • Scenario 5) tt    x    tt -----> F1) All short, tt
