BACKGROUND: Since prehistoric times Southern Italy has been a cultural
crossroads of the Mediterranean basin. Genetic data on the peoples of Basilicata
and Calabria are scarce and, particularly, no records on mtDNA variability
have been published. AIM: In this study mtDNA haplotypes of populations from
Basilicata, Calabria and Sicily are compared with those of other Italian
and Mediterranean populations, so as to investigate their genetic
relationships. SUBJECTS AND METHODS: A total of 341 individuals was analysed for mtDNA
in order to provide their classification into haplogroups. Multivariate
analysis was used to compare the studied populations with other Mediterranean
samples; median-joining network analysis was applied to observe the
relationship between the major lineages of the Southern Italians. RESULTS: The
haplogroup distribution in the Southern Italian samples falls within the typical
pattern of mtDNA variability of Western Eurasia. The comparison with other
Mediterranean countries showed a substantial homogeneity of the area, which is
probably related to the historic contact through the Mediterranean Sea.
CONCLUSION: The mtDNA analysis demonstrated that Southern Italy displays a
typical pattern of Mediterranean basin variability, even though it appears
plausible that Southern Italy was less affected by the effects of the Late Glacial
Maximum, which reduced genetic diversity in Europe.
