Genetic data from eight individuals offers a preliminary window into the biological heritage of these Nazari‑period Muslim communities. Y‑DNA results (R: 2, E: 1, CT: 1) suggest mixed paternal ancestries: R lineages are common across Iberia and Europe, whereas haplogroup E is often associated with North African and Mediterranean populations. CT here denotes a broad upstream lineage where downstream resolution is limited in these samples.
Mitochondrial diversity (U:3, H:2, H1:1, L:1, W6a:1) reveals predominantly Western Eurasian maternal lineages (U, H, W6a) alongside one L lineage indicative of sub‑Saharan maternal input. This pattern is consistent with historical records of Mediterranean mobility, the trans‑Saharan and Atlantic slave trades, and centuries of Iberian–Maghrebi contact. Archaeological DNA indicates admixture at the household level, but with only eight samples conclusions are tentative. Sampling bias, preservation, and laboratory resolution affect haplogroup calls; broader datasets are needed to clarify kinship, population structure, and the timing of admixture events.
