Maternally, the Masalit entirely belong to African-based derivatives of the
macrohaplogroup L according to Hassan (2010). Of these mtDNA clades, the
L0a1 (14.6%) and
L1c (12.2%) lineages are most frequent. According to Hassan et al. (2008), around 71.9% of Masalit are carriers of the
E1b1b paternal haplogroup. Of these, 73.9% bear the V32 subclade. Approximately 6.3% also belong to the haplogroup
J1. This points to significant patrilineal gene flow from neighbouring
Afro-Asiatic-speaking populations. The remaining Masalit are primarily carriers of the
A3b2 lineage (18.8%), which is instead common among
Nilotes. This altogether suggests that the genetic introgression into the Masalit's ancestral population was asymmetrical, occurring primarily through Afro-Asiatic-speaking males rather than females. ==Notable Masalit people==
