Analysis of the D1S80 locus by amplified fragment length polymorphism technique in the Chinese, Malays and Indians in Singapore.

The distributions of the D1S80 alleles and genotypes in the Chinese, Malays and Indians in Singapore were determined by amplified fragment length polymorphism (AMP-FLP) analysis. The distributions of the observed genotypes for the three races conformed to Hardy-Weinberg expectations. The system was applied to 19 families whose paternity had been established by restriction fragment length polymorphism (RFLP) analysis. In all cases, Mendelian inheritance of the alleles at the D1S80 locus could be demonstrated. D1S80 typing on DNA recovered by differential extraction of forensic specimens which included vaginal swabs, urethral swabs and seminal stains yielded consistent results.
