If a pea plant is tall, and tallness in pea plants is dominant over shortness, what is the phenotype of the pea plant?

The height of the plant is controlled by two alleles - the dominant 'T' for tallness and recessive 't' for shortness of the plant. The dominant allele represses the expression of the recessive allele. The recessive allele is expressed only in the homozygous state (tt)
