The aim of the ''Dauphiné Project'' is to reconstruct, with a wide perspective and multidisciplinary approach, the anthropological history of some mountain populations in both the French and Italian parts of the Dauphiné. Mountain populations present peculiarities that make them interesting to anthropology: living in difficult climatic conditions, continuous biological and socio-economic adaptation.
 The present study is an analysis of some seroprotein markers in blood samples of subjects living in mountain communities in the Western Alps and native to the area for at least two generations.
 The data for these seroprotein systems are the first results of the biological study of populations of the Western Alps. Thus they are an important contribution to our otherwise scanty knowledge about the distribution of these polymorph isms in the populations under study.
