Extended haplotype homozygosity (EHH) graph for Holstein cattle. EHH values in Holstein evaluating the decay of LD on either side of the core haplotypes. Values plotted as a function of increasing marker distance. Markers BTA-35050 and BTA-35941 were used to make up the candidate region near acyl-CoA:diacylglycerol acyltransferase 1 (DGAT1). Marker positions are represented in mega base pair (Mbp). The pink plot represents haplotype AC with 15.1% frequency. The blue plot represents haplotype GA with 16.9% frequency. The yellow plot represents haplotype AA with 33.7% frequency. The light blue plot represents haplotype GC with 34.3% frequency.
