A step back in time!!!

IN 1900, AN AUSTRIAN SCIENTIST NAMED KARL LANDSTEINER DISCOVERED THE BLOOD TYPES IN HUMANS. HE FOUND THAT WHEN RED BLOOD CELLS FROM DIFFERENT PERSONS  ARE MIXED, SOME INTERMINGLE WHILE OTHERS AGGLUTINATE OR CLUMP TOGETHER. HE ALSO FOUND THAT CERTAIN PROTEINS CALLED ANTIGENS ON THE MEMBRANE OF RED BLOOD CELLS CAUSE AGGLUTINATION.

IT'S A FACT!!!

**PHENOTYPE comes from the Greek words 
   "PHAINO" which means appear,
                    and 
   "TYPOS" which means image or shape....

**The blood group of a human is an example
    of a PHENOTYPE which cannot be seen outwardly...
