SANZ, A. et al. Structure and genetic relationships between Serrana de Teruel breed and other cattle breeds reared in Spain. Arch. zootec. [online]. 2011, vol.60, n.231, pp.369-372. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922011000300013.

In this work we analyze by microsatellite markers the genetic diversity, structure and relationships of the indigenous endangered Serrana de Teruel cattle breed with different breeds reared in Spain. All loci were polymorphic and a total of 198 alleles were observed across loci, with a mean of 6.79. Observed and expected heterozygosities values shown the high variability of Serrana de Teruel breed with values of 0.67 and 0.68 respectively. The neighbour net based on Reynolds distances shown the close genetic relationship among Serrana de Teruel and the mountain Parda de Montaña and Pirenaica breeds. STRUCTURE results showed a 47.5% of correctly assigned individuals to Serrana de Teruel breed using a q>0.8 threshold. The admixed animals shown a clear influence of Parda de Montaña breed.
