Study Published on Cambodian Ethnic Groups - Khmer, Cham, Khmer-Loeu
Open Access
Published: 24 May 2021
An in-depth analysis of the mitochondrial phylogenetic landscape of Cambodia

Abstract
Cambodia harbours a variety of human aboriginal populations that have scarcely been studied in terms of genetic diversity of entire mitochondrial genomes. Here we present the matrilineal gene pool of 299 Cambodian refugees from three different ethnic groups (Cham, Khmer, and Khmer Loeu) deriving from 16 Cambodian districts.
After establishing a DNA-saving high-throughput strategy for mitochondrial whole-genome Sanger sequencing, a HaploGrep based workflow was used for quality control, haplogroup classification and phylogenetic reconstruction. The application of diverse phylogenetic algorithms revealed an exciting picture of the genetic diversity of Cambodia, especially in relation to populations from Southeast Asia and from the whole world.

Even reading the label in the abstract I can’t figure out how to read that map.

Still doesn’t make any sense, unless the assumption is that every region on the map is ethnically 100% homogenous - or at any rate that the sampling methodology they’ve used is more than a little suspect. I’m hoping it’s just a badly conceived map, because the alternative is that they’ve really ballsed up the study.Places of birth of samples from three different ethnic groups (Khmer, Cham, Khmer-Loeu). Additionally, the sampling locations of Zhang et al. are represented, thereby outlining the lack of Cambodian samples.
