Figure 1From: Vietnamese chickens: a gate towards Asian genetic diversityMinimum spanning tree of the Vietnamese mtDNA haplotypes combined with the Chinese mtDNA from Liu et al . [7]. Circle size corresponds to haplotype frequencies. Haplotypes that are not found in the HG populations are in yellow, those that have been observed in wild populations are written in red. When haplotype is found both in the HG population, and in Chinese provinces, proportions are indicatedBack to article page
