HI.A antigens are encoded on chromosome 6p, and this is the most polymorphic system
in the human body.
Thus, antibodies in these sera detected a polymorphic system
of antigens on human leucocytes.
Human leukocyte antigens (HLA) are a highly polymorphic system
of glycoproteins that have a functional role in the presentation of peptides to the immune system.
(7) It was clear that this was a polymorphic system
beyond previous thought.
We tried to evaluate this new polymorphic system
for diagnostic testing of HNPP.
Finally, the degree of differentiation according to ABO/Rh polymorphic systems
was quantified for all seven populations (Nei, 1987).
Some qualitive and quantative characters and their relationship with each other in Germany Black Pied cattle populations, II polymorphic systems
The frequencies of these polymorphic systems
represent the genetic structure of a population (6).
The degree of differentiation among the five populations according to ABO/Rh polymorphic systems
was calculated (Nei, 1975), and the results were displayed in unweighted pair group method with arithmetic mean (UPGMA) dendrogram (Sneath and Sokal, 1973).
Phylogenetic trees constructed on the polymorphic systems
of the populations using the methods of Nei and Reynolds were found similar whereas Cavalli-Sforza was different figure.
