Detailed explanation-1: -Rh factor s follow a common pattern of genetic inheritance. The Rh-positive gene is dominant (stronger) and even when paired with an Rh-negative gene, the positive gene takes over. If a person has the genes + +, the Rh factor in the blood will be positive.

Detailed explanation-2: -This is because Rh-is something called a recessive trait. This means that someone who is Rh+ might have a hidden Rh-in their DNA. If that person and his or her partner both pass an Rh-down to a child, that child will be Rh-.

Detailed explanation-3: -Rh antigens are well developed at birth and are inherited as autosomal dominant genes.

Detailed explanation-4: -The Rhesus factor, or Rh factor, is a certain type of protein found on the outside of red blood cells. People are either Rh-positive (they have the protein) or Rh-negative (they don’t have the protein). This is important when you’re Rh-negative and pregnant with a fetus who’s Rh-positive.

Detailed explanation-5: -Rh(null) is a rare autosomal recessive disorder characterized by an absence of Rh antigens and a varying degree of hemolytic anemia and spherostomatocytosis.
