Abstract
Serum samples of the 3 tribal Negrito populations in the Philippine Islands (127 from Zambales, 87 from Bataan, and 93 from Agusan) were tested fro G1m(1,2,3 and 17), and G3m(5,6,11,13, 14,15,16 and 21), and Km(1). The GM pattern of the Negritos was characterized by 3 haplotypes, Gm1,7;21, Gm1,2,17;21 and Gm1,3;5,11,13,14, which is also characteristic of Mongoloid-related populations, especially with high incidence of the latter haplotype. They also have the haplotype, Gm1,17;5,13,14, prevalent in Africa, New Guinea and northern Australia, suggesting an ancient link between the Negritos and the New Guinean-Australian group. Two unusual samples of G3m(15) positive without G3m(16) observed in Zambales Negritos suggest the presence of Gm1,17;5,11,13,14,15 haplotype in the population. This appears to be unique to Zambales Negritos and the 1st such samples to be found.
