R1b-DF27 haplotaldearen hedapen mapa Europan

R-DF27 haplotaldea, R1b1a2a1a2a ere deitua, Y kromosomaren giza-haplotaldeetako bat da, S250 izenez ere ezagutzen den DF27 markatzailearen presentziak definitzen duen R1b haplotaldearen azpibanaketa dena.

Duela 4.200 urte inguru, Neolitoak Brontze Aroari bide eman zionean, Iberiako ipar-ekialdean garatu zela uste dute. DF27 azpitaldeak zeltiberiarrek osatutako erromatarren aurreko erresumekin estu lotuta daude.[1]

Gaur egun nagusi da Pirinio Atlantikoetan, Euskal Herrian, Asturiasen, Galizian, Portugalen, Aragoin eta Katalunian, eta presentzia txikia du Frantzian eta ehuneko txikietan Alemanian eta Polonian. Laginketetan, euskaldunen % 70etan topatu zuten, % 40 iberiar populazioetan, baina azkar jaitsi zen Frantzian, % 6tik % 20ra.[2] Latinoamerikan ere aurkitu dute.[3]

Gutxienez 47 azpiklado identifikatu dituzte, guztiak mendebaldeko europarrak, eta horietatik 19 inguru Iberiaren tipikoak direlarik.[4] R-M167, katalanei lotua, eta R-M153, euskaldunei lotua, DF27ren azpiklado espezifikoak dira.[5]
