Yes, in that study of African, European, Asian, Australian, and Papuan
samples they found the DYS389m segment to be highly informative for
identification of indigenous descent. They also stated DYS390m and -p
segments discriminate Asians, Papuans, and Australians from each other and
from Whites and Africans. They further state that the value of the four
DYS390 segments has been neglected, probably because of ascertainment bias:
in Whites, all segments but DYS390n are invariant. Maybe the various testing
companies should make note of this and start segmenting these marker
results. It could be very useful for analyzing population differences.
Hopefully they are reading this.
