(A) Frequency distribution of observed DGAT1 SNP haplotypes in the Dutch (blue) and New Zealand (red) Holstein-Friesian dairy cattle populations. The correspondence with the previously defined “Q” and “q” QTL alleles (Farnir et al. 2002) is shown. (B–D) Frequency distribution of the combined microsatellite (BULGE09-BULGE11) andSNP DGAT1 haplotypes. The previously definedHQ-D and HQ-NZ haplotypes (Farnir et al. 2002) are shown.
