    Allele Frequencies at the D2S44, D10S28 and D14S13 Loci in Four Southern African Populations

    Polymorphic DNA arising from variations in the number of short tandem repeats accounts for many of the hypervariable regions detected in the human genome (Nakumura et. al., 1987). For this preliminary study we...

    DNA Ty** — Strategies in Paternity and Forensic Casework

    Since 1972 we have tested 7272 cases of doubtful paternity. Most cases were adequately resolved by testing the conventional red cell antigen, plasma protein, red cell enzyme and HLA polymorphisms. During the l...

    Polymorphism of HLA-DRB3 and DRB4 Genes Detected by RFLPs

    All the characterized human HLA class II genes are encoded within the major histocompatibility complex (MHC) on the short arm of chromosome six. Among the five subregions of the class II region, HLA-DR is uniq...
