[QUOTE]Originally posted by Firewall: [QB] This what Wikipedia had to say. Modern Nile Sudanese Nubians [QUOTE] According to Y-DNA analysis by Hassan et al. (2008), around 44% of Nile Nubians in Sudan carry the haplogroup J. The remainder mainly belong to the E1b1b clade (23%). Both paternal lineages are also common among local Afroasiatic-speaking populations. The next most frequent haplogroups borne by Nubians are the Western European-linked R1b clade (10%) and the Eurasian lineage F (10%), followed by the archaic African B haplogroup (8%) and the Europe-associated I clade (5%). Maternally, Hassan (2009) observed that approximately 83% of their Nubian samples carried various subclades of the Africa-centered macrohaplogroup L. Of these mtDNA lineages, the most frequently borne clade was L3 (30.8%), followed by the L0a (20.6%), L2 (10.3%), L1 (6.9%), L4 (6.9%) and L5 (6.9%) haplogroups. The remaining 17% of Nubians belonged to sublineages of the Eurasian macrohaplogroups M (3.4% M/D, 3.4% M1) and N (3.4% N1a, 3.4% preHV1, 3.4% R/U6a1).[31] Analysing a different group of Nubian individuals inhabiting Sudan, Non (2010) found a significantly higher frequency of around 48% of the Eurasian macrohaplogroups M and N. Of these mtDNA lineages, 16% of the examined Nubians belonged to the M clade (around 9% to M1), with the rest bearing N subhaplogroups (including approximately 8% R0, 3% T1a, and 1% H). The remaining 52% of Nubians carried various Africa-centered macrohaplogroup L(xM,N) derivatives, with about 11% of individuals belonging to the L2a1 subclade. Dobon et al. (2015) identified an ancestral autosomal component of West Eurasian origin that is common to many modern Nubians and Afroasiatic-speaking populations in the Nile Valley and Horn of Africa, including Sudanese Arabs. Known as the Coptic component, it peaks among Egyptian Copts who settled in Sudan over the past two centuries. The scientists associate the Coptic component with Ancient Egyptian ancestry, without the later Arabian influence that is present among other Egyptians. Hollfelder et al. (2017) also analysed various populations in Sudan and similarly observed close autosomal affinities between their Nubian and Sudanese Arab samples. In 2015, Sirak et al. also analysed the ancient DNA of a Christian-period inhabitant of Kulubnarti in Nubia. The scientists found that the medieval specimen was most closely related to Middle Eastern populations. Further excavations of two Early Christian period (AD 550-800) cemeteries at Kulubnarti, one located on the mainland and the other on an island, revealed the existence of two ancestrally and socioeconomically distinct local populations. Ancient DNA analysis of specimens from these burial sites found that the mainland samples predominantly carried European and Near Eastern mtDNA clades, such as the K1, H, I5, and U1 lineages; only 36.4% of the mainland individuals belonged to African-based maternal haplogroups. By contrast, 70% of the specimens at the island burial site bore African-based clades, among which were the L2, L1 and L5 mtDNA haplogroups. [/QUOTE]I am still too not clear with the modern nubians in egypt but it is clear most nubians in sudan do not have arab admixture.By the way to make clear [b]R1b [/b]in sudan comes from blacks and has nothing to do with white europeans or white asians. In that study they are really talking about nubians from nile valley in sudan not hill nubians or nubians from darfur,so the study is is misleading.It's not talking about all nubians in sudan. If the nubians from from noba and darfur region the outside admixture rate goes down. Note-most noba are not nubians,but some are.They are called hill nubians. https://en.wikipedia.org/wiki/Nubians Note-some say most modern nubians of egypt do not admixture from white but it's ould be alarge grou that do and even if most do have admixture and large number do not.
