When was human blood group genetics first understood?
Quick Answer
The ABO blood group system was described in 1900, and the genetics behind inheritance were established in the early 20th century. It became one of the first clear examples of human heredity.
The Full Story
Karl Landsteiner identified the ABO blood group system in 1900, showing that incompatible blood types could cause dangerous reactions. In the years that followed, scientists worked out how blood groups were inherited through genes. This made ABO one of the earliest and most important examples of human genetic inheritance. The work had major consequences for transfusion medicine and human genetics.
