A total of 220 persons belonging to the Kolam tribe in the Adilabad District of northwest Andhra Pradesh have been tested for 18 red cell eyzyme systems and for haemoglobin. Generally, the gene frequencies for the systems which showed electrophoretic variation were within the range for Indian populations; the gene frequency for AK1 is high by Indian standards and Hb AS is present. LDH Calcutta 1 was not detected in this population and a single example of PHI 2-1 was observed.
