Fig. 3From: The genetic basis of discrete and quantitative colour variation in the polymorphic lizard, Ctenophorus decresii Sire-offspring regressions (a, b) and dam-offspring regressions (c, d) of proportion of orange (a, c) and yellow (b, d) components of throat colouration. Heritability (h2) is given by the slope of the regression. Grey shading shows 95Â % confidence intervals around the slopeBack to article page
