how are the plant height genotypes TT and Tt similar?

Question

both are examples of heterozygous genotypes
both are expressed as a short phenotype
both are examples of homozygous genotype
both are expressed as a tall phenotype

Answer 1

The statement "both are expressed as a short phenotype" is incorrect. The TT genotype is homozygous dominant for tall height, while the Tt genotype is heterozygous and also expresses the tall phenotype.
