Answer:

The phenotype of Tt would be tall.

It can be explained with the help of law of dominance which states that the dominant allele expresses itself completely over the recessive allele in heterozygous condition.

The dominant allele is represented by a capital letter. For example, T is a dominant trait which codes for tallness. It expresses its trait in homozygous as well as heterozygous condition.

The recessive allele or trait is represented by small letter and required homozygous recessive condition for their expression. For example, t is a recessive allele which codes for shortness when present in homozygous condition.

Thus, plants with TT and Tt will be tall in nature whereas plants with tt will be short or dwarf in nature.
