(a) Environment and genetic contribution to metabolites in the β-oxidation pathway. The x-axis is a list of the even-chain acylcarnitines, the y-axis is the negative log₁₀ of the P-value for the correlation coefficients. The dotted line represents the genetic component and the solid line represents the environmental component. (b) Environment and genetic contribution to metabolites along the pathway that represents the catabolism of the branched chain amino acids (valine and total leucine) into C3-DC and C4-DC. The x-axis is a list of the metabolites, the y-axis is the negative log₁₀ of the P-value for the correlation coefficients. The dotted line represents the genetic component and the solid line represents the environmental component.
