Fig. 2From: The genetic basis of discrete and quantitative colour variation in the polymorphic lizard, Ctenophorus decresii Parent-offspring regressions of the proportion orange and yellow components of throat colouration. Heritability estimate (h2) is given by the slope of the regression: A) orange h2 = 0.88, p < 0.001; B) yellow h2 = 0.60, p = 0.0002. Grey shading shows 95 % confidence intervals around the slopeBack to article page
