Detailed explanation-1: -The notation tt means the homozygous condition, wherein the homologous pair contains same alleles of a gene.
Detailed explanation-2: -Individuals who are homozygous dominant (DD) or heterozygous (Dd) are Rh+. Those who are homozygous recessive (dd) are Rh-(i.e., they do not have the key Rh antigens). Clinically, the Rh factor, like ABO factors, can lead to serious medical complications.
Detailed explanation-3: -Genotype = genes present in an organism (usually abbreviated as two letters) TT = homozygous = pure. Tt = heterozygous = hybrid.
Detailed explanation-4: -So, the correct answer is D “Tt".
Detailed explanation-5: -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. Q. Q.
