Original sentence: 2005, sub-Saharan mtDNA L haplogroups were found at rates of 3.83% in Iberians (Portuguese and Spanish),  2.86% in Sardinians, 2.38% in Albanians, 1% in the British,  0.94% in Sicilians, 0.62% in a German-Danish sample.According to a summary study by Pereira et al.By contrast, North Africans have about 5% paternal West African admixture, and are about of 75% paternal East African descent.Haplotype A has been detected in Portugal (3%), Spain (0.42%), Germany (2%), Austria (0.78%), France (2.5% in a very small sample), Italy (0.45%), Sardinia (1.6%) and Greece (0.27%).However, Haplogroups E(xE3b) and Haplogroup A spread to Europe due to migrations from Northeast Africa, rather than the slave trade.It ranges from a few percent in Iberia to almost nil around the Baltic.It seems to show a decreasing cline from the southwest to the northeast, which corresponds with the areas most affected by the African slave trade.Nevertheless, The amount of black admixture in Europe today is low.Sub-Saharan African Y-chromosomes are much less common in Europe, for the reasons discussed above
