Demographics of Cuba - Genetics

Genetics

A 1995 study done on the population of Pinar del Rio, found that 50% of the Mt-DNA lineages (female lineages) could be traced back to Europeans, 46% to Africans and 4% to Native Americans. This figure is consistent with both the historical background of the region, and the current demographics of it.

Regarding Y-chromosome haplogroups (male lineages), 78.8% of the sequences found in Cubans are of West Eurasian origin, 19.7% of African origin and 1.5% of East Asian origin. Among the West Eurasian fraction, the vast majority of individuals belong to West European haplogroup R1b. The African lineages found in Cubans have a Western (haplogroups E1, E2, E1b1a ) and Northern (E1b1b-M81 ) African origin. The "Berber" haplogroup E1b1b1b (E-M81), is found at a frequency of 6.1%.

According to Fregel et al. (2009), the fact that autochthonous male North African E-M81 and female U6 lineages from the Canaries have been detected in Cuba and Iberoamerica, demonstrates that Canary Islanders with indigenous ancestors actively participated in the American colonization.
