From: Biased estimators of quantitative trait locus heritability and location in interval mapping

Histograms of the estimators of QTL location resulting from the search over a 225 cM chromosome. Panels (a)–(c) are based on all 500 replicates. Panel (d) is based on 187 significant replicates. Heritability is h2=0.03 and the sample size is 200. Means of estimators of QTL location in panels (a)–(d) are marked by ‘O’, and are equal to 55.9, 111.7, 174.8, and 31.6, respectively. True values of QTL location are marked by ‘X’ (22.5, 112.5, 202.5, 22.5, respectively).
