title: A cline in the acid phosphatase1 distribution in the Iberian Peninsula.
abstract: Blood samples from autochthonous and unrelated persons were examined for acid phosphatase (ACP1) phenotypes. The subjects were 143 Spanish Basques, 118 people from León and 295 from Castile. The samples were typed using starch gels, with one surface coloured with phenolphthalein diphosphate (Na5 salt) and the other surface revealed with 4-methylumbelliferyl-dihydrogenphosphate. The gene frequencies observed are compared with those obtained by other authors.
