Haploview representation of pairwise linkage disequilibria spanning a 1.9-Mb region at the MSTN gene locus in Thoroughbred horses. Linkage disequilibria structure of 47 SNPs is shown for (a) All Thoroughbreds (n=397) (b) C/C Thoroughbreds only (n=102) and (c) T/T Thoroughbreds only (n=80). Blocks were defined using the confidence interval method. The SNP ID is displayed along the top of the diagram. Colours represent D′ values (dark red=high inter-SNP D′; blue=statistically ambiguous D′; white=low inter-SNP D′), and r2 values are contained within blocks (bold=high r2). In Thoroughbreds the C-allele was observed on a single haplotypic background spanning 932 kb; the T-allele was observed on 10 haplotypic backgrounds.
