 The remainder of the Ulchi mitochondrial DNA pool comprises haplogroups N9b (7/160 = 4.4%), M8a (6/160 = 3.75%), F1a (5/160 = 3.1%), M7 (4/160 = 2.5%), M9a1 (1/160 = 0.6%), Z1a2(xZ1a2a) (1/160 = 0.6%), and B5b2 (1/160 = 0.6%).Besides a very high frequency of mtDNA haplogroup Y1a among the Ulchi, they also have a greater proportion of C5 than C4b or C4a, unlike the Udege, Evens, or Evenks.The haplogroup D mtDNA of the Ulchi is very diverse, but the most frequently observed subclade is D4o2, which Duggan "et al."
