Detailed explanation-1: -As the given genotype is Tt, it’s a heterozygous condition and in heterozygous condition the dominant trait (T-tall) will express itself. Hence, the phenotype of Tt will be a tall plant.
Detailed explanation-2: -If an organism has two different alleles ( Tt ) for a certain gene, it is known as heterozygous (hetero-means different). Phenotype is a way to describe the traits you can see.
Detailed explanation-3: -The notation tt means the homozygous condition, wherein the homologous pair contains same alleles of a gene.
Detailed explanation-4: -The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
Detailed explanation-5: -Answer: because it has two different allele.
