Rh Positive (Rh+) and Negative (Rh-) Blood Types The Rh (+/-) factor is inherited separately from the ABO blood types. If one parent has A and another has O, they can either produce a child with A or O blood types. It should be noted that while the ABO and the Rh+ and Rh- blood type group systems are the ones we are most familiar with, there are way more ways to classify our blood types. What Is The Most Common Blood Type There are eight different blood types and each one holds a unique power to save lives. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. Blood type B makes up only 10% of the population, while blood type AB is the rarest at 4%. Pregnancy Sometimes problems can occur when a mother’s blood does not match her baby’s. Blood type B+ is more common in Asians (25) and less common in Latin Americans and Caucasians (both at 9). In comparison, only 39 of Asians, and 37 of Caucasians have this type. They are: Red blood cells (Erythrocytes) White blood cells (Leukocytes) Platelets (Thrombocytes) 1. Antibodies (also called immunoglobulins) are specialized proteins that identify and defend against foreign intruders to the body. Up to 53 of Latin Americans and 47 of African Americans have blood type O+. Blood is composed of the blood cells which accounts for 45 of the blood tissue by volume, with the remaining 55 of the volume composed of plasma, the liquid portion of the blood. These blood groups are determined by the antigen on the blood cell surface and the antibodies present in the blood plasma. Using data from Wikipedia and the Standford Blood Center, Reddit user foiltape put together this pie chart that shows the most common and least common blood types in the US:Īnd here's a more precise percentage breakdown from most common to least common blood types in the US:Īnd if you disregard the Rh+ and Rh- blood type classification system, and just look at O, A, B and AB blood types the most prevalent blood type in the US is blood type O (44%), with blood type A at a close second (42%). There are four main ABO blood type groupings: A, B, AB, and O. Therefore we see that the most common blood group in India is O positive. In general, blood type O-positive is the most common blood type in the world, while AB-negative is considered the rarest, but does this trend apply to the blood type distribution in the US? Here is the average blood type distribution in the Indian population. It was found that Basques have the highest concentration of type O blood in the world more than 50 of the population, with an even higher percentage in.
