Both are examples of homozygous genotypes.

Both are examples of heterozygous genotypes.
Both are examples of heterozygous genotypes.

Both are expressed as a tall phenotype.
Both are expressed as a tall phenotype.

Both are expressed as a short phenotype.
Both are expressed as a short phenotype.

Answer 1

The correct response is:

**Both are expressed as a tall phenotype.**

Genotypes TT (homozygous dominant) and Tt (heterozygous) both express the dominant trait, which in this case is tall height for the plants.
