Y-DNA

According to
Y chromosome studies by Sanchez et al. (2005), Cruciani et al. (2004, 2007), the Somalis are paternally closely related to other
Afro-Asiatic-speaking groups in
Northeast Africa.
[175][176][177] Besides comprising the majority of the Y-DNA in Somalis, the
E1b1b (formerly E3b)
haplogroup also makes up a significant proportion of the paternal DNA of
Ethiopians,
Sudanese,
Egyptians,
Berbers,
North African Arabs, as well as many
Mediterranean populations.
[176][178] Sanchez et al. (2005) observed the M78 (E1b1b1a1) subclade of E1b1b in about 70.6% of their Somali male samples.
[175] According to Cruciani et al. (2007), the presence of this subhaplogroup in the Horn region may represent the traces of an ancient migration from
Egypt/
Libya.
[177]
After haplogroup E1b1b, the second most frequently occurring
Y-DNA haplogroup among Somalis is the West Asian
haplogroup T (M184).
[179] The clade is observed in more than 10% of Somali males generally,
[175] with a frequency peak among Somalis in
Dire Dawa (82.4%)
[180] and
Djibouti (~74%).
[181] Haplogroup T, like haplogroup E1b1b, is also typically found among other populations of Northeast Africa, the
Maghreb, the
Near East and the Mediterranean.
[182]
mtDNA

According to
mtDNA studies by Holden (2005) and Richards et al. (2006), a significant proportion of the maternal lineages of Somalis consists of the
M1 haplogroup.
[183][184] This mitochondrial clade is common among Ethiopians and North Africans, particularly
Egyptians and
Algerians.
[185][186] M1 is believed to have originated in Asia,
[187] where its parent M clade represents the majority of mtDNA lineages.
[188] This haplogroup is also thought to possibly correlate with the Afro-Asiatic language family:
[184]
"We analysed mtDNA variation in ~250 persons from Libya, Somalia, and Congo/Zambia, as representatives of the three regions of interest. Our initial results indicate a sharp cline in M1 frequencies that generally does not extend into sub-Saharan Africa. While our North and especially East African samples contained frequencies of M1 over 20%, our sub-Saharan samples consisted almost entirely of the L1 or L2 haplogroups only. In addition, there existed a significant amount of homogeneity within the M1 haplogroup. This sharp cline indicates a history of little admixture between these regions. This could imply a more recent ancestry for M1 in Africa, as older lineages are more diverse and widespread by nature, and may be an indication of a back-migration into Africa from the Middle East."
[184]
Autosomal DNA

According to an
autosomal DNA study by Hodgson et al. (2014), the Afro-Asiatic languages were likely spread across Africa and the Near East by an ancestral population(s) carrying a newly identified non-African genetic component, which the researchers dub the "Ethio-Somali". This Ethio-Somali component is today most common among Afro-Asiatic-speaking populations in the Horn of Africa. It reaches a frequency peak among ethnic Somalis, representing the majority of their ancestry. The Ethio-Somali component is most closely related to the Maghrebi non-African genetic component, and is believed to have diverged from all other non-African ancestries at least 23,000 years ago. On this basis, the researchers suggest that the original Ethio-Somali carrying population(s) probably arrived in the pre-agricultural period from the Near East, having crossed over into northeastern Africa via the
Sinai Peninsula. The population then likely split into two branches, with one group heading westward toward the
Maghreb and the other moving south into the Horn.
[189] Ancient DNA analysis indicates that this foundational ancestry in the Horn region is akin to that of the Neolithic farmers of the southern
Levant.
[190]
HLA antigens
The analysis of
HLA antigens has also helped clarify the possible background of the Somali people, as the distribution of haplotype frequencies vary among population groups.
[191] According to Mohamoud et al. (2006):
[192]
"HLA antigens of the Somali population are not categorised as well as those of other international ethnic groups. We analysed the HLA antigens of 76 unrelated Somalis who lived in the west of England. HLA -A, -B, -C and DRB1 typing was performed by polymerase chain reaction using sequence-specific oligonucleotide probes (PCR-SSOP) at a low-intermediate resolution level. Phenotype frequency, gene frequency and haplotype frequency were used to study the relationship between Somalis and other relevant populations. The antigens with highest frequencies were HLA -A1, A2, and A30; B7, B51 and B39; Cw7, Cw16, Cw17, Cw15 and Cw18; DR 13, DR17, DR8 and DR1. HLA haplotypes with high significance and characteristics of the Somali population are B7-Cw7, B39-Cw12, B51-Cw16, B57-Cw18. The result of HLA class I and class II antigen frequencies show that the Somali population appear more similar to Arab or Caucasoid than to African populations. The results are consistent with hypothesis, supported by cultural and historical evidence, of common origin of the Somali population."
