From: Linkage disequilibrium in crossbred and pure line chickens
Decay of linkage disequilibrium with distance on different categories of chromosomes in different populations. Each population is represented by a different color. Each point in the plots represents the mean r 2 of marker pairs in a 25-kb interval. Points representing field and pedigree crossbred and combined BCD populations (purple, grey and cyan, respectively) are almost overlapping and difficult to distinguish in most areas.
