| Abstract: | Y chromosome-specific DNA polymorphisms were detected using probe p49f after restriction with TaqI enzyme on samples coming from two African populations: Bantus and Pygmies. All the main TaqI alleles at five Y loci already found in Caucasians are also found in these two populations; 12 of the 16 Caucasian haplotypes were found in these two African populations, and two new haplotypes are Pygmy specific. A proposed phylogeny of the various haplotypes that was derived by using the parsimony criterion established that haplotypes XIII and XVIII, respectively the most frequent one and only one present in Pygmies, are probably ancestral. |
