Figure 3.

A gene’s noise and plasticity are correlated. Multiple regression analyses in Tables 1 and 2 use Model 1 regression, but with reversed dependent and independent variables. For such a weak correlation, plasticity as a function of noise is quite different from the inverse function of noise as a function of plasticity: both lines are shown here. In the absence of a correlation, the functions describing these two lines would be horizontal and vertical, respectively. For comparison, the Model 2 Standard Major Axis regression line is also shown. The correlation between noise and plasticity is tighter in the top right corner, where values of both are high [11].
