Up to 173 African sires belonging to 11 different subpopulations representative of four cattle groups were analysed for six Y-specific microsatellite loci and a mitochondrial DNA fragment. Differences in Y-chromosome and mtDNA haplotype structuring were assessed. In addition, the effect of such structuring on contributions to total genetic diversity was assessed. Thirty-five Y-chromosome and 71 mtDNA haplotypes were identified. Most Y-chromosomes analysed (73.4%) were of zebu origin (11 haplotypes). Twenty-two Y-haplotypes (44 samples) belonged to the African taurine subfamily Y2a. All mtDNA haplotypes belonged to the "African" taurine T1 haplogroup with 16 samples and nine haplotypes belonging to a recently identified subhaplogroup (T1e). Median-joining networks showed that Y-chromosome phylogenies were highly reticulated with clear separation between zebu and taurine clusters. Mitochondrial haplotypes showed a clear star-like shape with small number of mutations separating haplotypes. Mitochondrial-based F -statistics computed between cattle groups tended to be statistically non-significant (p > .05). Most F values computed among groups and subpopulations using Y-chromosome markers were statistically significant. AMOVA confirmed that divergence between cattle groups was only significant for Y-chromosome markers (Φ = 0.209). At the mitochondrial level, African sires resembled an undifferentiated population with individuals explaining 94.3% of the total variance. Whatever the markers considered, the highest contributions to total Nei's gene diversity and allelic richness were found in West African cattle. Genetic structuring had no effect on patterns of contributions to diversity.

Dual Origins of Dairy Cattle Farming – Evidence from a Comprehensive Survey of European Y-Chromosomal Variation

et al. 2011

BackgroundDiversity patterns of livestock species are informative to the history of agriculture and indicate uniqueness of breeds as relevant for conservation. So far, most studies on cattle have focused on mitochondrial and autosomal DNA variation. Previous studies of Y-chromosomal variation, with limited breed panels, identified two Bos taurus (taurine) haplogroups (Y1 and Y2; both composed of several haplotypes) and one Bos indicus (indicine/zebu) haplogroup (Y3), as well as a strong phylogeographic structuring of paternal lineages.Methodology and Principal FindingsHaplogroup data were collected for 2087 animals from 138 breeds. For 111 breeds, these were resolved further by genotyping microsatellites INRA189 (10 alleles) and BM861 (2 alleles). European cattle carry exclusively taurine haplotypes, with the zebu Y-chromosomes having appreciable frequencies in Southwest Asian populations. Y1 is predominant in northern and north-western Europe, but is also observed in several Iberian breeds, as well as in Southwest Asia. A single Y1 haplotype is predominant in north-central Europe and a single Y2 haplotype in central Europe. In contrast, we found both Y1 and Y2 haplotypes in Britain, the Nordic region and Russia, with the highest Y-chromosomal diversity seen in the Iberian Peninsula.ConclusionsWe propose that the homogeneous Y1 and Y2 regions reflect founder effects associated with the development and expansion of two groups of dairy cattle, the pied or red breeds from the North Sea and Baltic coasts and the spotted, yellow or brown breeds from Switzerland, respectively. The present Y1-Y2 contrast in central Europe coincides with historic, linguistic, religious and cultural boundaries.

“…This supports the scenario of a contribution to domestic cattle in Africa from regional wild males. The Pérez Pardal et al (2009Pardal et al ( , 2010 data suggest the existence of several different wild sire populations with poor phylogeographic differentiation within the continent, but distinctive from those of Southwest Asia.…”

“…Studies of Ethiopian cattle showed that African breeds have higher Y-chromosomal haplotype diversity than is found in European breeds. Pérez Pardal et al (2009Pardal et al ( , 2010 presented comprehensive studies on genetic diversity in African and European cattle breeds, including not only Y-chromosomal microsatellites but also Y-chromosomal SNP genotypes (cf.

Whether cattle domestication occurred independently on the African continent is among the most controversial questions in the Holocene archaeology of northern Africa. One long-established scenario, based upon early archaeological evidence, suggested that Africa's earliest cattle derived from several introductions from Southwest Asia through the Nile Valley, or via the Horn of Africa. Based upon archaeofaunal remains retrieved in the late twentieth century, other archaeologists argued that an independent domestication of the African aurochs gave rise to Africa's earliest domestic cattle. Up to now, the genetic data have also been controversial. This paper reviews the archaeological evidence and the scope of debate, and then focuses on the recent contributions of genetic research to clarifying these issues.Résumé S'il y'eût eté une domestication independent des bovins dans le continent Africain perdure comme un question conflictuel dans l'archéologie Holocène d'Afrique. Une hypothèse bien établie dans la literature, et bien fondé sur l'évidence archéologique recouvré dans la premier parte du vingtième siècle, est que les bovins plus anciens dans l'Afrique etaient derivés de plusiers introductions du sud-oest d'Asie au Vallé du Nil o à la Corne de l'Afrique. Autres archéologues, utilisant des témoignages d'archéofaunes retrouvés pendant la dernière parte du vingtième siècle, prétendaient qu'une domestication independente des aurochs autochtones à l'Afrique etait la source du grand betaîl originel du continent. Néanmois l'évidence génétique était sujet a débattre entre les specialists. Cet article commence en résumer les débats et les evidences archéologiques, et après axe sur les contributions récentes des études du génome bovin à élucider l'histoire du grand betaîl dans l'Afrique.
