Six major haplogroups (R, I, E, J, G, and DE) were detected, being R-S116 (P312) haplogroup the most abundant at 75.0% in Alava, 86.7% in Guipuzcoa and 87.3% in Vizcaya.

Basal DE* is extremely unusual in that it is found, at very low frequencies, among males from three widely separated regions: West Africa, the Caribbean, and Asia.
A 2003 study by Weale et al., of the DNA of over 8,000 males worldwide, found that five out of 1,247 Nigerian males belonged to DE*. The DE* found possessed by these five Nigerians, according to the study's authors, was "the least derived of all YAP chromosomes according to currently known binary markers" – to such an extent that it suggested that DE had originated in West Africa and expanded from there. However, Weale et al., cautioned that such inferences may well be incorrect. In addition, the seemingly "paraphyletic" (basal) status of the Nigerian examples of DE-YAP may be "illusory" because the "branching order, and hence the origin, of YAP-derived haplogroups remains uncertain". It was "easy to misinterpret apparently paraphyletic groups", and subsequent research might show that the Nigerian examples of DE were as divergent from DE*, D* and E*. "[T]he only genealogically meaningful definition of the age of a clade is the time to its most recent common ancestor, but only if DE* is [truly] paraphyletic does it ... become automatically older than D or E..." The relationship between DE*, according to Weale et al., "can be viewed as a missing-data problem..."[11] In 2007, another West African example of DE* was reported – carried by a speaker of the Nalu language who was among 17 Y-DNA samples taken in Guinea Bissau. The sequence of this individual differed by one mutation from those of the Nigerian individuals, indicating common ancestry, although the relationship between the two lineages has not been determined.[12]
In 2008, a basal paternal marker belonging to DE* was identified in two individuals from Tibet (two out of 594), belonging to the Tibeto-Burman group.[13]
A 2010 study found six additional samples of DE*(xE) (a DE lineage that did not belong to the E branch) in southeastern Nigeria in individuals of the Ibibio, Igbo, and Oron ethnic groups.[14]
In 2012, haplogroup DE* was found in one Caribbean sample.[15]
