RT Journal Article T1 Genetic Structure of the Ca Rater Mallorquí Dog Breed Inferred by Microsatellite Markers A1 García, Lourdes Sofía Aguilera A1 Vergara, Amado Manuel Canales A1 Herrera, Pedro Zurita A1 Puente, José Manuel Alanzor A1 Barro, Águeda Laura Pons A1 Dunner Boxberger, Helene Susana A1 Marques, Carlos San José A1 Bermejo, Juan Vicente Delgado A1 Martínez, Amparo Martínez AB Ca Rater Mallorquí is a dog breed from the Island of Mallorca (Spain) traditionally used as a hunting and ratting dog to prevent disease spread and economic losses related to rodent activities on farms. However, the census data shows a population decline that should be addressed by implementing a conservation program. The first step to implementing a conservation plan is knowing the genetic situation of the Ca Rater Mallorquí population. Therefore, we aimed to genetically characterise the breed in our study. We analysed 33 microsatellites recommended by the International Society of Animal Genetics (ISAG) in 77 samples. Data were obtained from 13 samples of Balearic, Spanish, and international dog breeds to study the genetic diversity among breeds. The population did not significantly deviate from the Hardy–Weinberg equilibrium with heterozygosity (Ho) of 0.655 and expected heterozygosity (He) of 0.685. The Wright’s fixation indices, the Factorial Correspondence Analysis (FCA), a dendrogram representing Reynolds genetic distance between populations, and the pairwise FST values establish the Ca Rater Mallorquí as an independent breed distinct from the Balearic, Spanish, and international breeds.
