The scope of blood genetic marker investigations in paternity testing in Chinese and Malays

The chance of excluding from paternity a falsely accused Chinese man and a falsely accused Malay man by using a number of blood genetic marker systems have been calculated using the ABO, Rhesus and MNSs systems, the combined chances are. 46.4% for a Chinese and 50.2% for a MaIay. When serum protein and red cell enzyme systems are included, the chances increase to approximately 76%. The chances may be increased by testing for haemoglobin variants, by red cell typing for the Diego (Di^a)
antigen, and by testing for phenotypes other than Gm(a) in the Gm system. The Kell system may in some circumstances provide evidence in favour of paternity.
