Explanation:
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: -So, the correct answer is D “Tt".
Detailed explanation-4: -Homozygous and Heterozygous If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait.
Detailed explanation-5: -So, the correct option is ‘50%’.
