FIGURE 1

Circular Manhattan plot for associations of SNP with ewe composite traits at birth by two GWAS approaches. The 6 circles from outside to inside represent Progeny Birth Weight (PBW): pGWAS and eGWAS; Total Litter Weight at Birth (TLWB): pGWAS and eGWAS; Litter Mean Weight at Birth (LMWB): pGWAS and eGWAS. The outermost circle shows SNP density in the 1 Mb window for each chromosome. X-axis: SNP positions on chromosomes, Y-axis: –Log10 P-value. The red and blue dashed lines indicate the thresholds for genome-wide (1.22*10–5) and chromosome-wide (P < 1.67*10–4) statistical significance, respectively. The red and blue dots show associated and suggestive SNPs, respectively. pGWAS: GWAS using phenotypes as a response variable; eGWAS: GWAS using EBVs as a response variable.
