Predominance of A group in Brahmins and B group in Kammas is observed. Phenotype A2 records less than 4% in both populations. High frequencies of genes M, s, D, and e are exhibited among both populations. Statistically significant differences are found only for A1A2BO system between Brahmins and Kammas. |
