ABSTRACT
The aim of this work was to perform a thorough analysis of the diversity of Y-haplotypes in Spanish cattle. A total of 207 Bos taurus males were sampled across 25 European breeds, with a special focus on rare, local Spanish populations. Animals were genotyped with five Y-specific microsatellites (INRA189, UMN0103, UMN0307, BM861 and BYM1), two indels (ZFY10 and USP9Y) and one SNP (UTY19). A new haplogroup, distinct from those described by Götherström et al. (2005), was identified and named Y1.2. Samples representing the three B. taurus Y-haplogroups were genotyped for four additional Y chromosome SNPs (rs121919254, rs121919281, rs121919323 and rs137049553). Among these SNPs, only rs121919281 was informative in B. taurus and helped to confirm the new Y1.2 haplogroup. Analysis of a larger dataset of standardized haplotypes for 1507 individuals from 57 populations from Spain, other European countries and Africa showed the new Y1.2 haplogroup to be found exclusively in Spanish breeds. This finding reinforces the importance of local Spanish cattle as reservoirs of genetic diversity as well as the importance of the Iberian Peninsula in the history of cattle.
