[DNA polymorphism and paternity exclusions: analysis of 543 cases of paternity testing]

The study of the genetic markers of polymorphism has known a very large evolution during these last ten years in relation to the development of the molecular biology and the discovery and analysis of some DNA repeated loci. In a study of 543 of paternity testing, the authors analyse the performance of some probes, the limits of their using, the program and strategy of testing to establish a high probability of exclusion.
