Figure 2.
The simulation results for case-control data with varying prevalence (K) and number of QTLs. The x axis quantifies the genetic architecture for the base population, in which the cases and the controls are sampled. The y axis represents the heritability on the liability scale. The x axis reflects the genetic architecture: negative/positive LD indicates the repulsion/coupling genetic architecture; LD=0 indicates the neutral genetic architecture. Of note, when , it was under the repulsion genetic architecture.
