Linkage disequilibrium of the OAR2_128282778.1 surrounding 5.4 Mb, which have 4 haplotype blocks. SNP pairs are coloured according to the standard Haploview colour scheme: D = 1, red; D’<1, other colours. LOD>2 and D’ = 1, red; LOD>2 and D’ <1, shades of pink/red; LOD <2 and D’ = 1, blue; LOD <2 and D’<1, white (LOD is the log of the likelihood odds ratio, a measure of confidence in the value of D’).
