Show Answer
Correct Answer: D [A person with this blood group may receive blood only from a person with O blood group]
Notes:
Hh or the Bombay blood group, is a rare blood type. This blood phenotype was first discovered in Bombay, now known as Mumbai, by Dr. Y. M. Bhende in 1952. It is mostly found in South Asia (India, Bangladesh, Pakistan) and parts of Middle East such as Iran. Individuals with the rare Bombay phenotype (hh) do not express H antigen (also called substance H), the antigen which is present in blood group O. For this reason people who have Bombay phenotype can donate red blood cells to any member of the ABO blood group system but they cannot receive blood from any member of the ABO blood group system but only from other people who have Bombay phenotype.
