title: New Q lineage found in bovine (Bos taurus) of Iberian Peninsula.
abstract: The northern Iberian Peninsula is home to a variety of autochthonous cattle breeds, such as the Terreña and Pirenaica. With the objective of characterizing the matrilineal lineages of these breeds, a study of mitochondrial DNA was performed. The D-loop of 155 individuals was analyzed and most of the individuals were carriers of the T3 haplogroup, while haplogroups T and T1 were much less frequent. A Pirenaica individual belonging to the Q haplogroup was found. To verify the presence of the Q haplogroup individual, the entire mitochondrial DNA was sequenced and compared with two descendants. The individuals were assigned to the Q1 sub-haplogroup. These findings extend the geographic distribution of the Q haplogroup to the south west of the European continent. This new Q1 lineage has seven polymorphisms in the coding region, so this lineage is probably as old as the Q lineages described to date.
