Figure 2.

Correction for the bias of estimated QTL heritability. The simple linear model was used in the simulation (without polygenic background control). There are four levels of the test threshold (t = 10, 15, 20, 25) and the sample size is n = 100. The noisy curves are the average estimated QTL heritability from 40 replicated simulation experiments. The smooth curves are the predicted QTL heritability. The red curves are the QTL heritability prior to the correction for the Beavis effect (deviated from the diagonal). Blue curves are the QTL heritability after correction for the Beavis effect (closer to the diagonal).
