Studies of the impact of post‐marital residence patterns on the distribution of genetic variation within populations have returned conflicting results. These studies have generally examined genetic diversity within and between groups with different post‐marriage residence patterns. Here, we directly examine Y chromosome microsatellite variation in individuals carrying a chromosome in the same Y haplogroup. We analyze Y chromosome data from two samples of Yemeni males: a sample representing the entire country and a sample from a large highland village. Our results support a normative patrilocality in highland Yemeni tribal populations, but also suggest that patrilocality is violated often enough to break down the expected correlation of genetic and geographic distance. We propose that a great deal of variation in male dispersal distance distributions is subsumed under the “patrilocal” label and that few human societies are likely to realize the idealized male dispersal distribution expected under strict patrilocality. In addition, we found almost no specific correspondence between social kinship and genetic patriline at the level of the clan (large, extended patrilineal kinship group) within a large, highland Yemeni village. We discuss ethnographic accounts that offer several cultural practices that explain exceptions to patrilocality and means by which social kinship and genetic patriline may become disentangled. © 2013 Wiley Periodicals, Inc.
