Phylogenetic tree for the haplotypes within the narrowed region in whole genome sequenced animals. Asian animals (green) are homozygous for haplotype 1 or 1-like, whereas European animals (red) have both haplotypes. European cluster of animals within the Asian animals group (yellow) shows that the haplotype 1 (low androstenone) originated from Asian breeds.
