According to an mtDNA study by Shah et al. (2011), the maternal ancestry of the Siddi consists of a mixture of Sub-Saharan and Indian haplogroups, reflecting substantial female gene flow from neighboring Indian populations. About 53% of the Siddis from Gujarat and 24% of the Siddis from Karnataka belonged to various Sub-Saharan macro-haplogroup L sub-clades. The latter mainly consisted of L0 and L2a sublineages associated with Bantu women. The remainder possessed Indian-specific subclades of the Eurasian haplogroups M and N, which points to recent admixture with autochthonous Indian groups.
