From: Performance of a blockwise approach in variable selection using linkage disequilibrium information
Blockwise dependency in real genotyping data: 256 SNPs spanning the first 1.45 Mb of Chromosome 6 in [11]. The average distance between two successive SNPs is approximately 5 kb. The upper triangular part of the matrix displays measures of LD (r 2 coefficients) between pairs of SNPs, while its lower triangular part displays absolute sample correlations between pairs of SNP genotypes. Colors range linearly from 0 (white) to 0.4 (black).
