What is the probability of having a b negative blood group?
Answers
When a person's blood is analyzed under a microscope distinct blood differences are visible. In the early 20th century, an Austrian scientist named Karl Landsteiner classified blood according to those differences. Landsteiner observed two distinct chemical molecules present on the surface of the red blood cells. He labeled one molecule "A" and the other molecule "B".
Blood Types (Groups)
A blood type (also called a blood group) is defined as the classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). A series of related blood types constitutes a blood group system, such as the Rh or ABO system. The frequencies of the ABO and Rh blood types vary from population to population.
Blood Type A - If the red blood cell has only "A" molecules on it.
Blood Type B - If the red blood cell has only "B" molecules on it.
Blood Type AB - If the red blood cell has a mixture of both "A" & "B" molecules.
Blood Type O - If the red blood cell has neither "A" or "B" molecule.
