From: Linkage disequilibrium in crossbred and pure line chickens
Correlation of LD on different chromosome categories among the pure lines and crossbred populations. Each population is represented by a different color. Each point in the plots represents the mean correlation of r in a 50-kb interval. Points representing the correlations of r between field and pedigree crossbred populations and combined BCD populations are almost overlapping and difficult to distinguish in some areas.
