Prediction of the Sex-Associated Genomic Region in Tunas (Thunnus Fishes)

Figure 7

Genome-wide association with copy number between PBT males and females. The mapping of resequenced reads was conducted using a masked male reference. The plots on scaffold M175 are indicated by triangles. (a) Differences in regional copy number between males and females are denoted as the values of in the Mann–Whitney test. Upward plots indicate that the copy number is larger in males than in females, while downward plots indicate the inverse. Genome-wide significance cutoffs based on Bonferroni correction are indicated by dashed lines. (b) Manhattan plot (left) and Q-Q plot (right) from CNV-based GWA scan. The regions with copy number 0, 0.5, or 1 were selected ( values lower than 10^-15 were treated as 10^-15). In the Manhattan plot, genome-wide significance cutoff based on Bonferroni’s correction is indicated by a red line.
