My point remains unaffected by your interesting remarks. The Basques were isolated from the mainstream Spaniards even during the 700 year Moorish occupation. Selecting them as representative of the original Spanish genotype, prior to intermingling with Moors, Jews, and others after 1492 is an unproven assumption, thus the confound.
Also, Spaniards have other strains as well-such as Celtic and Roman.
