aChromosome
bPosition of QTL region
cNumber of SNPs within the QTL region
dPercentage of genetic variance explained by the QTL region
eSemen traits: MOT: sperm motility; PROMOT: sperm progressive motility; lnNcells: number of sperm cells per ejaculate; ABN: total morphological abnormalities
fThe percentage of genetic variance explained by the QTL region is < 1%. When the variance is reported for more than one trait, the QTL region is overlapping across traits
gBest candidate gene(s) in the region
hNo candidate genes associated with the trait
