Figure 3From: High-resolution association mapping of number of teats in pigs reveals regions controlling vertebral developmentGenetic variance explained per chromosome. The variances explained by the defined QTL regions as in Table 1 are shown in blue ( σ QTL 2 ). The variances explained by SNPs when placed in the second distribution (π1) are shown in orange ( σ g 1 2 ). The variances explained by SNPs when placed in the null distribution (π0) are shown in grey ( σ g 0 2 ). The variances of the SNPs were summed per chromosome.Back to article page
