A Y-chromosome study by Shah et al. (2011) tested Siddi individuals in India for paternal lineages. The authors observed the E1b1a haplogroup, which is frequent amongst Bantu peoples, in about 42% and 34% of Siddis from Karnataka and Gujarat, respectively. Around 14% of Siddis from Karnataka and 35% of Siddis from Gujarat also belonged to the Sub-Saharan B haplogroup. The remaining 30% of Siddi had Indian or Near Eastern-associated clades, including haplogroups H, L, J and P.

Thangaraj (2009) observed similar, mainly Bantu-linked paternal affinities amongst the Siddi.
