In pea plants, the allele for tall height, T, is dominant over the allele for short height, t. A pea plant has two different alleles for height. Which statement about the pea plant is correct?

The correct statement about the pea plant is that it will display the tall phenotype.

so do i put TT

No, if a pea plant has two different alleles for height, it cannot be TT. TT would indicate that the plant has two dominant alleles for tall height. Since the plant has two different alleles, one of them must be the dominant allele T and the other must be the recessive allele t. Therefore, the correct genotype for the pea plant would be Tt.

so is the phenotype tall or short

Since the allele for tall height (T) is dominant over the allele for short height (t), the phenotype of the pea plant with the genotype Tt would be tall.

ok so here is my answer

the phenotype for hight is tall, and the genotype is Tt is this correct

Yes, that is correct! The phenotype for height would be tall, and the genotype would be Tt. Well done!
