🇹🇭 Genetic Landscape of Thailand
Thailand's genetic landscape reflects its position at the heart of mainland Southeast Asia, with Tai, Mon-Khmer, Malay, Chinese, and indigenous hill-tribe ancestry creating subtle but real genetic variation. The Thai-Chinese community (up to 15% of the population) adds East Asian genetic influence, while southern Thai populations show Malay genetic markers. Thailand's hill tribes — Karen, Hmong, Lisu, Akha — each carry distinct genetic signatures from their migration histories across Tibet, China, and Myanmar.
