We report on a comparison of the genetic diversity between Ibiza and the
population of the other Balearic islands and also between the archipelago with
respect to circum-Mediterranean populations. For such a comparison, autosomal and
Y-chromosome STRs, as well as mtDNA sequence data analyzed from the same
individuals, were studied. Analysis of 14 autosomal STRs showed that Ibiza had
significant differentiation with respect to other Balearic populations and also
with respect to insular and continental populations from the Mediterranean
area. Nevertheless, the results obtained from the analysis of eight Y-STRs showed
a high level of genetic homogeneity for eight western Mediterranean
populations. On the other hand, these populations did not show a compacted group when
mtDNA diversity was analyzed, since they showed genetic differentiation among
them. The analyses of haplotypes shared between populations indicated that mtDNA
haplotypes have drifted to higher frequencies than the Y chromosome. This
fact could be due to a shared recent history between Ibiza and other western
Mediterranean populations, with numerous male displacements originated by wars
and, especially, commercial relations. The results of mtDNA from the Ibiza
population could be due to a maternal Carthaginian/Phoenician founder effect,
together with genetic drift, in accordance with the historical and demographic data
of the area.
