According to Y-DNA analysis by Hirbo (2011), around 82.6% of Gabra in Kenya carry the paternal E1b1b haplogroup, with most belonging to the V12 or E3b1a subclade (58.6%). This lineage is most common among local Afroasiatic-speaking populations. The remaining Gabra individuals bear the T/K2 (3.4%) and J haplogroups (3.4%), which are both also associated with Afroasiatic speakers, as well as the E3*/E-P2 clade (3.4%) and E2a lineage (3.4%).[9]
Maternally, Hirbo (2011) observed that approximately 58% of the Gabra samples carried derivatives of the Eurasian macrohaplogroups M and N. Of these mtDNA lineages, the M1 subclade was most common, with around 22.58% of the Gabra individuals belonging to it. The remaining ~42% of the analysed Gabra bore various subclades of the Africa-centered macrohaplogroup L. Of these mtDNA lineages, the most frequently borne clade was L3 (19.36%), followed by the L0a (9.68%), L4 (9.68%), and L2 (6.45%) haplogroups.[9]
The Gabra's autosomalDNA has been examined in a comprehensive study by Tishkoff et al. (2009) on the genetic affiliations of various populations in Africa. According to Bayesian clustering analysis, the Gabra generally grouped with other Afroasiatic-speaking populations inhabiting Northern Kenya.[10]
