Who devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations?.
SVEN [57.7K]

Leone Lattes devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations.

An easy technique for identifying the blood type of a dried bloodstain was invented in 1915 by the Italian scientist Leone Lattes.

In 1939–1940, the Rh blood group system—which divides blood into groups depending on whether the Rh antigen is present or not—was created. Since then, more than a hundred various blood factors have been identified.

These characteristics can be utilized to pinpoint the particular groups to which possible suspects may belong because they show up unevenly in the population.

As different blood factors are identified in a sample, the proportion of individuals who have that particular combination of factors decreases and the sample becomes more unique.
