HEMOTYPOLOGICAL STUDY OF THE ALGERIAN POP ULATION IN THE ABO, P AND LUTHERAN SYSTEMS

An hemotypological study of the Algerian population has been carried o ut in the ABO, P and Lutheran systems. The red blood cell phenotyping by micromethods involved 4 444 subjects for the ABO system, 4 484 for the P system, and 4 303 for the Lutheran system. Gene frequencies were determined for each Wilaya of the country. In the ABO system, the val ues vary from 0.1315 to 0.2721 for A allele, from 0.0849 to 0.1615 for B allele, and from 0.6054 to 0.7388 for O allele. In the P system, th e values of P1 gene vary from 0.5254 to 0.6201. In the Lutheran system , the values of Lu-a allele are not exceeding 0.0326. The Algerian pop ulation is generally characterised by a A gene of intermediate frequen cy between those of Caucasoids and Negroids, a B gene of frequency clo se to that of Negroids, and O and P1 genes of frequencies close to tho se of Caucasoids.
