which describes the notation tt for the trait of plant height?\no homozygous genotype\no heterozygous…

Brief Explanations:

In genetics, a genotype is the genetic makeup. When an organism has two different alleles (T and t in this case) for a trait, it is heterozygous. Phenotype is the observable trait. Here, Tt represents the genetic combination (genotype), not the observable trait. So it is a heterozygous genotype.

Answer:

heterozygous genotype
