The plant height genotypes TT and Tt are similar in that they both are expressed as a tall phenotype.
Here's a breakdown of the terms:
- TT (homozygous dominant) and Tt (heterozygous) both result in the tall trait if T (the dominant allele) is the allele for tallness.
- They are not both examples of homozygous genotypes; TT is homozygous, but Tt is heterozygous.
- Neither genotype is expressed as a short phenotype; both are associated with the tall phenotype due to the presence of at least one dominant T allele.
Therefore, the correct option is: **Both are expressed as tall phenotype.**
