Manhattan plots depicting the genetic associations between SNPs and the sperm quality traits that showed genome-wide significant values. Significant associations have been found with the percentage of: a Percentage of cells with head abnormalities (HABN); b percentage of cells with abnormal acrosomes after 5 min incubation at 37°C (ACRO_5); c percentage of cells with neck abnormalities (NABN); d percentage of motile spermatozoa after 5 min incubation at 37°C (MT_5); e Percentage of motile spermatozoa after 90 min incubation at 37°C (MT_90); f Percentage of cells with proximal droplets (PDROP); g Ratio of the percentage of abnormal acrosomes at 5 min versus 90 min incubation times (R_ACRO). The x-axis represents chromosome length (Mb), and the y-axis shows the negative log10 P-values of the genetic associations. The horizontal red line represents the significance threshold (FDR ≤ 0.05)
