Abstract

The mitochondrial DNA (mtDNA) and Y-chromosome (NRY) haplogroup composition, as well as the surname distribution in Santa Maria and Flores Islands (Azores Archipelago, Portugal), were analysed. Both mtDNA and NRY haplogroup distribution display significant differences between the two islands. For mtDNA, gene diversity was higher for Flores. NRY diversity derived from haplogroups, as well as the heteronymy values were statistically lower for Santa Maria. Rst values indicated reduced levels of microdifferentiation within both islands. Integration of previous results with those obtained in the present study further reinforced the fact that the different Azorean islands cannot be considered as a whole homogeneous population. © 2005 Elsevier B.V.
