From: Heritability of siesta and night-time sleep as continuously assessed by a circadian-related integrated measure

Figure 2

Proportion of variance explained by genetic and environmental factors for the different sleep parameters studied. The pie slices represent the contribution (percentage) of broad heritability (A = additive genetic factor + D = non-additive genetic factors), and non-shared environmental factors (E) to the phenotypic variance of the different variables. CFI: circadian function index. Variables are sorted by function group.
