This Article Black African genetic contribution to the population of the European continent explains how genetic markers that are common among sub-saharans can be found at low frequencies in parts of the European Continent: Y-DNA Haplogroups A, B and certain subclades of E (esp. E3A) are considered to be characteristic of sub-Saharan populations These haplotypes are found at frequencies of less than 1% in every part of Europe studied. Although Haplogroups A and B are undeniable considered to Sub-Saharan haplogroup E is thought to represent a migration from Asia to Africa Interestingly haplogroup E is closer related to the Eurasian y-dna haplogroups then it is to sub-saharan african y-dna haplogroups with both E and the eurasian y-chromosomes being desendents of CT while the sub-saharan A and B haplogroups are not. . Mtdna Mtdna haplogroup (L) which is the only mtDNA haplogroup that is considered to be sub-saharan, is much more common in Europe then all of the sub-Saharan y-dna haplogroups combined . Even so it is quite rare in Europe: Where it is found at a frequency of less than 1% in all nations in Europe that where studied except for Portugal where a few percent of people have it.
