(A) Decay of linkage disequilibrium (R²) is shown relative to genetic distance (cM). The decay function is the mean for all pairs of markers with a genetic distance equal to or less than the value on the X axis. Pale blue dots in the background are marker pairwise R² values. (B) LD decay is shown relative to physical distance for pairs of markers mapped to the same contigs of the Pita v.2.01 reference genome.
