Document Summary
Human populations + movement of humans of humans. Human marriage customs fit into 2 cultural trends: patrilocality: females move to location of their male spouse, matrilocality: males move to location of their female spouse. Contrasting movement trends determined by culture, society, religious. Less variation because no male gene flow (male not moving) * genetic differentiation = genetic differences between population. If males always moving to new locality, will be more variation within population on y chromosome because males move there from all over the place. Males moving a lot, won"t see a lot of genetic differences on. Y chromosome, because a lot of gene flow on y chromosome as males move around. Males stay put, not a lot of movement, will see more genetic differences between populations at y chromosome b/c no mixing. Y chrom differentiation between populations mtdna variation within populations mtdna differentiation between populations.
