Figure 2From: A missense mutation in growth differentiation factor 9 (GDF9) is strongly associated with litter size in sheepQQ-plot of p -values without the GDF9 c.1111G>A SNP included. Comparison of p-value distributions when all the 47 986 analyzed Illumina SNPs were included (A), and the corresponding plot when 2 112 SNPs on chromosome 5 were excluded (B). The expected –log10(p) is on the x-axis and the observed –log10(p) is on the y-axis.Back to article page
