An international watershed in the publication and discussion of genetic evidence for ancient movements of people was that of Luigi Luca Cavalli-Sforza who used polymorphisms from proteins found within human blood (such as the ABO blood groups, Rhesus blood antigens, HLA loci, immunoglobulins, G-6-P-D isoenzymes, amongst others).
The ABO blood group system is determined by what type of glucosyltransferases are expressed in the body.
In addition to its effects on chloride secretion, which involve the same steps as the effects of cholera toxin, heat-labile enterotoxin binds additional substrates: lipopolysaccharide on the surface of E. coli cells and A-type blood antigens.
A number of vaginal, anal, and vulval swabs were taken by the pathologist, and subsequent forensic examination confirmed the presence of semen, from which the blood type of the killer was determined.

Blood type – The semen samples taken from Linda's body provided a match with Shirley's blood group, O positive, although this group was shared by 23.3% of the British adult male population.
In humans it is the terminal carbohydrate forming the antigen of blood group A.
The scientists reported that the man, dubbed "Inuk", had A+ blood type, genes suggesting he was adapted to cold weather, had brown eyes, brownish skin, dark hair, and would likely bald later in life.
Uncommon in Australia, some of the people of this tribe have the B blood type.
