Variability of blood group frequencies in Romania

This paper presents the results of a study of two population samples from Dobruja and Muntenia (Romania) as well as data from the literature (AB0, MN, Rhesus (D/d) and HPA). The data have been pooled according to the different regions of Romania. Interestingly, the Carpathian Mountains do not form a genetical barrier: there are clear genetical similarities between the provinces east and west as well as between the provinces south and north from the mountains. The differences and similarities between Romania as a whole and other populations in this region reflect the historical processes of the last centuries.
