The distribution of the ABO genotypes and phenotypes in Singapore in 1987.
The aims of this study are to determine for the 3 main ethnic groups in Singapore: a) the ABO phenotype distribution in 1987 b) the A, B and O gene frequencies c) the proportion of A and B group individuals who are homozygous using (i) temporal studies (trial & error) (ii) the derived A and B gene frequencies This paper presents the method of study and the results obtained using a sample of 39,019 blood donors in 1987. The opportunity has also been taken to compare the data derived in this study with that quoted in 2 previous studies.
