Genome-wide association study (GWAS) of sex reversal of half-smooth tongue sole of ZTW genotype on SNP Cyn_Z_6676874. The x-axis represents the genomic coordinates along chromosomes 1–20 and sex chromosomes W and Z. The y-axis represents the negative logarithm of P-values. The horizontal dashed line is the genome-wide threshold; SNPs above this line are significantly associated with sex reversal
