Genome-wide association analysis and chromosome distribution of sex-associated SNPs. (A) Manhattan plots depicting GWAS results associated with sex of A. japonicus. The x-axis shows the physical location of SNPs across the 23 chromosomes, and the y-axis shows the − log10 (P-value). The black threshold line represents P-value = 1-e4, the red threshold line represents P-value = 1-e6. (B) Chromosome distribution of sex-associated SNPs by GWAS. The x-axis depicts P-value thresholds (P < 1-e6), and the y-axis depicts the percentages of sex-associated SNPs per unit chromosome length for each chromosome
