Abstract
AbstractRomosinuano is a tropically adaptedBos taurusbreed, and some Mexican breeders aim to improve it genetically. The aim was to estimate allelic and genotypic frequencies for SNPs associated with meat quality in a Mexican Romosinuano population. Four hundred ninety-six animals were genotyped using the Axiom©BovMDv3 array. Only SNPs related to meat quality in this array were studied in this analysis. The Calpain, Calpastatin, and Melanocortin-4 receptor alleles were considered. Allelic and genotypic frequencies and Hardy-Weinberg equilibrium were estimated with the PLINK software. Alleles associated with meat tenderness and higher marbling scores were found in the Romosinuano cattle population. CAPN1_4751 was not found in Hardy-Weinberg equilibrium. The rest of the markers could not be affected by selection and inbreeding. Romosinuano cattle in Mexico have similar genotypic frequencies in markers related to meat quality toBos taurusbreeds known for their meat tenderness. Breeders can choose a marker-assisted selection to improve meat quality characteristics.
