Abstract

A survey of the blood groups of a Chilcotion band produced unexpected results for the ABO system (0.69 for allele 0, 0.31 for allele A), MNSs system (0.53 for antigen M, 0.47 for antigen N), P (0.36 for P1). Other loci surveyed were within the range of expectation. The frequency of phosphoglucomutase type PGMmath image was found to be 0.87, and for the dry cerumen allele 0.57. The frequency of the A allele was found to be decreasing among males, and several possibly distinctive characteristics of northern and southern Athapaskans are noted.
