Paternal lineage affinity of the Malay subethnic and Orang Asli populations in Peninsular Malaysia
Peninsular Malaysia is populated by the Malays, Chinese, Indians, and Orang Asli. We have analyzed 17 Y-STRs loci for 243 randomly unrelated individuals, which include 153 Malays (7 Acheh, 13 Champa, 11 Rawa, 9 Kedah, 23 Minang, 15 Bugis, 43 Kelantan, 14 Jawa, and 18 Bugis) and 90 Orang Asli [54 Semang (16 Kensiu, 13 Lanoh, 25 Bateq); 30 Senoi (21 Semai, 9 Che Wong); and 6 Proto-Malay (6 Orang Kanaq)] from selected settlements in Peninsular Malaysia using the AmpFlSTR Yfiler™ kit (Applied Biosystems™). The overall haplotype diversity is 0.9966, i.e., 0.9984 for the Malays and 0.9793 for the Orang Asli. A total of 158 haplotypes (65.02%) were individually unique. The p value and pairwise Rst analysis was calculated to show the genetic structure of the samples with other world populations (from YHRD website). Based on the Y-STR data, Champa, Acheh, Kedah, Minang, and Kelantan are clustered together. Lanoh and Kensiu (Semang) are very closely related, suggesting similar paternal ancestry. Jawa Malays and Indonesian Java, plus the Bugis Malays and Australian Aborigines shared high degree of paternal lineage affinity. This study presents data for very precious relict groups, who are the earliest inhabitants of Peninsular Malaysia.
