“…The current matrilocal and patrilocal residence patterns of the Besemah and Semende are documented since the middle of the 19th century [29][30][31] , but it is unknown when they were first established. It has been hypothesized that matrilocality is ancestral in Austronesian societies and that descendant groups of Austronesian people in the Pacific adopted a patrilocal residence pattern over time, as a switch from matrilocality to patrilocality is more common than the reverse change 32 .…”

Larger mitochondrial DNA than Y-chromosome differences between matrilocal and patrilocal groups from Sumatra

Genetic differences between human populations are typically larger for the Y-chromosome than for mitochondrial DNA (mtDNA), which has been attributed to the ubiquity of patrilocality across human cultures. However, this claim has been disputed, and previous analyses of matrilocal groups give conflicting results. Here we analyse mtDNA variation (complete mtDNA genome sequences via next-generation sequencing) and non-recombining regions of the Y-chromosome variation (Y-single-nucleotide-polymorphisms and Y-short-tandem-repeats (STR)) in a matrilocal group (the Semende) and a patrilocal group (the Besemah) from Sumatra. We find in the Semende significantly lower mtDNA diversity than in the Besemah as expected for matrilocal groups, but unexpectedly we find no difference in Y-chromosome diversity between the groups. We highlight the importance of using complete mtDNA sequences for such analyses, as using only partial sequences (as done in previous studies) can give misleading results.
