Figure 4
Relationship between narrow sense (additive) and broad sense heritability on the risk scale for different disease prevalences ( K ). From simulations of a single population of 106 individuals, with 
calculated as 4(λ
OG
- 1)K/(1-K) where λ
OG
is the recurrence risk of disease in grandchildren of affected grandparents and 
calculated from Equation 2.
