Fig. 4From: Analysis of genetic differentiation and genomic variation to reveal potential regions of importance during maize improvementSummary statistics of genetic variation existing in the whole set of accessions. ‘a’ is a picture of pair-wise kinship of the 1857 accessions. ‘b’ displays the decay level of linkage disequilibrium (LD) on different chromosomes and across the whole genome. ‘c’ shows the comparison of LD level between different subpopulations. ‘d’ pictures the genomic differentiation on Chromosome 8Back to article page
