Answer

Answer:

A. 0%

Explanation:

Step1: Understand the trait inheritance

Tall is dominant (TT or Tt), short is recessive (tt).

Step2: Analyze the offspring result

Offspring are all tall. If both parents were homozygous recessive (tt), all offspring would be short. Since all offspring are tall, both parents being homozygous recessive is impossible, so the probability is 0%.
