Fig. 2From: Genomic heterozygosity and hybrid breakdown in cotton (Gossypium): different traits, different effectsPairwise linkage disequilibrium between all markers in both populations. The r2 and p-values from linkage disequilibrium testing of the (3E) F2 (a) and (E3) F2 (b) are above the diagonal and below the diagonal, respectively. The r2 distributions in (3E) F2 (c) and (E3) F2 (d) are shownBack to article page
