16 Y-specific STR loci have been analysed in 711 males from 12 populations
in Pakistan. Individual loci showed between 4 and 10 alleles, and diversiti
es ranged from 0.01 to 0.77. A total of 527 different haplotypes were found
and the haplotype diversity ranged from 0.92 to 0.99 for the different pop
ulations. 446 haplotypes occurred in single individuals, and only 19 haplot
ypes were present in more than three males, but two striking examples of ha
plotype sharing were found, one involving 13 individuals, and the other 17.
The 13 individuals were all Parsis, and 16 of the 17 were Brahuis, providi
ng evidence for population substructuring. (C) 2001 Elsevier Science Irelan
