Sažetak
Detrimental impact of certain mitogenome mutations on sperm quality traits, and consequently on male fertility is well documented in humans. With a quantitative genetic mixed model, we analysed the impact of cytoplasmic eff ects, maternal lineages treated as random eff ect, on sperm quality traits in 554 Austrian Fleckvieh bulls. We have observed that 2% of the phenotypic variance for transformed total number of spermatozoa is due to cytoplasmic (maternal lineage) eff ects. Regarding percent of viable live spermatozoa, no cytoplasmic eff ects were detected. However, the observed eff ects still need to be further evaluated from three perspectives, the analysis of the mitogenome polymorphism eff ects and the impact of the mitogenome eff ects on the realised fertility as well as on the whole production economically
