Description Received: 2020-10-22 Accepted: 2021-02-08 Available online: 2021-02-28 study presents an approach to detect selection signals by the scan of runs of homozygosity (ROH) in two beef cattle populationsbred Slovakia. The frequency and distribution of runs of homozygosity in the genome are affected by natural and artificial selection,recombination rate and structure of the population. After quality control, the final data set included 43,427 single nucleotidepolymorphisms with overall length 2,504 Mb. Across the genome, sixteen regions under strong selection pressure with a totallength of 73.94 Mb were identified. The functional analysis of selection signals revealed several quantitative trait loci for bodystructure, fitness and milk production. In the region with a high frequency of ROH reflecting the intense artificial selection genesrelated mainly to muscle development (MSNT, ROCK1, LAMTOR5) were observed. Besides, genes related to the control of theimmune system (PTX3, FGL2) and reproduction (ADCYAP1R1) were localized within selection signals. The results confirm theintention to improve the production and reproduction traits of Charolais and Limousine cattle according to established breedingobjectives for each breed.Keywords: beef production, genomic region, homozygosity, quantitative traits, signatures of selectionReferencesClarke, A.M. et al.
