Resumen
In this study, we used BovineSNP50 Genotyping BeadChip data to estimate the structure, putative
ancestral origin as well as to identify regions with selective sweeps that may have had an important
role in the adaptation to tropical conditions of the ‘Charolais de Cuba’ (CHCU) breed. According to a
principal component analysis, CHCU samples cluster together with taurine breeds with an estimated
93% of taurus ancestral alleles. Despite the short period since importation, we detected diferentiation
(Fst= 0.049) between the French Charolaise (CHA) and CHCU. However, CHA breed was the closest
breed to CHCU followed by other hybrids breed with a clear CHA origin. Linkage disequilibrium (r2)
decay tends to be lower in CHCU compared to CHA probably due to a less intense artifcial selection
programs of CHCU. Signals of recent adaptation to tropical conditions between CHCU and CHA were
identifed. Genes mapping within those regions refect diferent functions related to immunity,
metabolic changes and heat tolerance (CHCU) and muscle development and meat quality (CHA) that
may have had an important role in the phenotypic diferentiation of these breeds. Further studies
will expand our knowledge on the molecular basis of adaptation of cattle to tropical conditions and
molecular process associated with meat quality traits.
