Paternal genetic landscape of contemporary Thai populations in the borderland provinces of Thailand and Myanmar.

ABSTRACT: This study investigates the genetic structure and demographic history of contemporary Thai populations from Tak and Ranong, two border provinces between Thailand and Myanmar with complex immigration histories. We analyzed 20 Y-SNP markers (327 samples) and 24 Y-STR profiles (241 samples), along with published datasets, and observed significant genetic differentiation between these regions. Tak is dominated by O2a2b1a1a (44.53%) and O1b1a1a (21.17%). The presence of NO1 (14.6%) suggests genetic contributions from nearby populations such as the Karen, Lawa, and Khuen. Notably, Tak shows low gene diversity (GD) at the DYS391 (0.2208), contrasting with Ranong (0.5247) and the overall Thailand population (0.4708). Ranong exhibits a more diverse haplogroup distribution, with prominent frequencie
