=== Autosomal DNA ===
A 2018 study of 400 adult men and women of all the islands, except La Graciosa, examined the relationship of Canarian genetic diversity with the more prevalent complex diseases in the archipelago. It detected that Canarian DNA shows distinctive genetics, resulting from variables such as the geographical isolation of the islands, environmental adaptations and the historical mixture of Pre-Hispanic population of the archipelago (coming from North Africa), with European and Sub-Saharan individuals. Specifically, the study estimated that the Canarian population, at an autosomal level, is 80% European, 17% North-African and 3% Sub-Saharan.<ref name="sociedad">{{Cite web |date=12 January 2019 |title=Cuatro apellidos canarios, un bisabuelo peninsular y otro africano |url=https://www.canarias7.es/sociedad/cuatro-apellidos-canarios-un-bisabuelo-peninsular-y-otro-africano-YH6339320 |access-date=17 March 2024 |website=[[Canarias7]] |language=es |archive-url= |archive-date=}}</ref>
