Analysis of Y-chromosomal short tandem repeat (Y-STR) polymorphisms among Orang Asli population in Taman Negara and Jerantut of Pahang / Siti Hajar Noor Alshurdin

Orang Asli in Peninsular Malaysia have different types of culture and belief, which impacted from history of migration centuries ago. They are three major sub-ethnic groups namely Negrito, Senoi and Proto-Malay. The main goal of this research is to study the genetic variation among Orang Asli popula...
