New Insights into the Lake Chad Basin Population Structure Revealed by High-Throughput Genotyping of Mitochondrial DNA Coding SNPs
Popis výsledku v původním jazyce
This study is based on 230 SNP polymorphisms of mitochondrial DNA (mtSNP) in 542 samples from 12 populations located in Lake Chad Basin and evaluates populations of nomadic pastoralists and sedentary farmers. We provided thus much better phylogenetic resolution than previous studies of this geographic region. Using a Bayesian framework the nomadic populations showed negative growth which was not always correlated to their estimated effective population sizes. Nomads also showed lower diversity values than sedentary groups. Compared to sedentary population of the African Sahel, nomads thus showed signals of stronger genetic drift occurring in their ancestral populations. It is also interesting that the nomadic populations showed a higher North African influence than the sedentary populations of the Lake Chad Basin.
