Figure 1.
Genome-wide association study for additive and dominance effects on number of teats in pigs.
On the y-axis is the −log10 (P-values) of single-SNP association with number of teats in pigs. On the x-axis is the physical position of the SNPs across the 18 autosomes. SNPs associated (false discovery rate ≤0.10) with number of teats having additive and dominance effects are represented by squares and triangles, respectively.

Figure 2.
Difference in linkage disequilibrium (LD) between two distinct QTL regions.
(a) LD (r2) between the significant SNPs of the QTL region on Sus Scrofa chromosome (SSC) 12; the most significant SNP in this region is surrounded by a square. (b) LD between the SNPs located 0.2 Mb downstream and upstream of the only significant SNP (surrounded by a square) of the QTL region on SSC4. The numbers inside the diamonds are the LD measurements (r2) on a scale of 0 to 100%.

Genotype effects and their standard errors of the most significant SNPs on Sus scrofa chromosomes (SSC) 4 and 7 on number of teats (NT). The genotypic effects are relative to the effect of the heterozygous genotype, which was set to zero.
