The Bovini tribe contains domestic and wild cattle-like species, several of which are cross-fertile. We present a completely resolved Y-chromosomal phylogeny, which is better in agreement with autosomal phylogeny, morphological data, cross-fertility and estimates of divergence times than mitochondrial data. The tree links Bos grunniens (yak) to Bison, so the commonly accepted Bos genus is not monophyletic. Therefore, we advocate the term Poephagus as designation of yak. This work illustrates the resolving power of Y-chromosomal variation for cladistic studies of closely related species. © The Willi Hennig Society 2008.
