Genetic diversity analysis of six Spanish native cattle breeds using microsatellites

Six native Spanish cattle breeds have been characterized by using 30 microsatellite markers. The studied populations can be divided into three groups: Brown orthoid (Asturian Mountain, Asturian Lowland and the Nord-west Brown Group), Red convex (Pyrenean and Menorquina) and the Iberian bovine (Fight...

Description
Summary:Six native Spanish cattle breeds have been characterized by using 30 microsatellite markers. The studied populations can be divided into three groups: Brown orthoid (Asturian Mountain, Asturian Lowland and the Nord-west Brown Group), Red convex (Pyrenean and Menorquina) and the Iberian bovine (Fighting bull). Allele frequencies were calculated and used for the characterization of the breeds and the study of their genetic relationships. Different genetic distance measures were calculated and used for dendogram construction. The closest populations were those representing Asturian breeds, the most divergent being Menorquina and Fighting Bull. The latter also showed the lowest diversity values (mean number of alleles per locus and heterozygosity). Genetic distances obtained between the other populations under analysis were similar to those reported for different European cattle breeds. This work analyzes the recent origin of these populations and contributes to the knowledge and genetic characterization of European native breeds.
