Genetic relationships of the Yucatan black hairless pig with Iberian breeds using single nucleotide polymorfisms

To conduct ex-situ creole pig conservation programs, it is essential to determine which breeding animals will be used, preferentially those with a more significant Iberian genetic component preserve their origin. This study used Yucatan black hairless pigs (YBHP) subpopulation estimate its diversity and population structure. One hundred four adult were selected for the absence of hair, skin (without spots), hoof, straight snout. The porcine-GGP-50K chip was SNP genotyping in YBHP, information on Yucatán from United States (USYU) taken databases. All analysis performed using PLINK v1.9 v2.1 software. Inbreeding fixation index values lower high observed heterozygosity allogamy values, agree obtained populations Canarias Chato Murciano. According clusters generated by “Genome-Wide Identity State” analysis, groups identified, one included Guadyerbas, USYU, YBHP. Between populations, YBHP closely related Canarias.
