Patterns of genetic diversity in humans (and other species) are heavily dependent on patterns of population movements and migrations. Oota et al. show how sex-biased patterns of migration influence genetic variation both in mitochondrial DNA (mtDNA), which is inherited through the maternal line, and in the Y chromosome, which is inherited through the male line. In the hill tribes of northern Thailand, some societies are matrilocal, which means that women stay in their birthplace, whereas men move to marry; others are patrilocal and the women move—a pattern more common in human societies. In patrilocal groups, mtDNA haplotype diversity was much higher than in the matrilocal groups, whereas the reverse was true of Y haplotypes. Thus, at a fine scale, social structure can determine genetic diversity in humans. — AMS
