Additional file 2: Figure S2. Identification of a common haplotype on BTA4. Description: Genotypes of a subset of 32 Weaver carriers and 13 Weaver-affected offspring were scanned for regions of homozygosity surrounding the main and secondary peaks. The segment of interest consisted of 197 SNPs between positions 44,387,787 and 47,598,264Â bp. Carets (^) indicate the position of the secondary peak (47,598,264Â bp), asterisks (*) indicate the position of the main peak (49,812,384Â bp). Red bars indicate shared haplotype segments, green bars indicate the common haplotype shared by both Weaver-affected and carrier animals.
