Figure 4. LDx predictions decay at a biologically plausible rate.

r² decays in a similar pattern among the direct estimation (red), maximum likelihood (blue) and DGRP (green) r² measures. Points represent average r² within distance classes. Averages were applied only to pairs that had minor allele frequency >0.1. Lines represent predicted decay or r² with physical distance. Decay models were fit in R 2.13 (R core Development Team 2012).
