Fig 3. Correlations analysis between expression levels of multi-tissue eQTLs.

To identify co-expression patterns between multi-tissue eQTLs, correlations of expression levels of genes associated with multi-tissue eQTLs was analysed by Spearman rank correlation analysis. Correlations were calculated from expression data from both liver and testis. Edges indicating correlation are shown for both liver and testis expression data. Green circles indicate filtered multi-tissue eQTLs with significant association to summarised EBVs for skatole and HNS. The two types of correlations are discerned by both colour and shape. Positive correlations between expression levels are indicated with dashed red line. Negative correlations between expression levels are indicated by a dashed green line. Boldness of lines indicates the degree of correlation. Only edges representing Spearman rank correlations above R² > 0.5 or below R² < -0.5 are shown.
