[Towards a genealogy of chromosome Y].

Taq I restriction polymorphisms of the 49 f genomic probe are used to establish a possible filiation of the Y chromosome in human populations. Relationships between alleles at the five polymorphic loci revealed by the probe allow the description of 17 haplotypes. Simulations are used to construct a plausible genealogy of these various haplotypes, on the basis of a limited set of basic hypotheses concerning polymorphic alleles evolution.
