Reduced-median network (Bandelt et al. 1995) for coding-region polymorphisms found in 894 samples belonging to haplogroup H, in the four segments described in the text. Mutations that define the H sub-haplogroups are shown in bold, and sub-clades are labeled. The area of each circle is proportional to the number of mtDNAs in the total sample harboring the corresponding haplotype. Geographic regions are as follows: AJ, Ashkenazi Jews; SW, Iberia; NW, France, Ireland, UK/US sample, Norway; Med, mainland Italy, Sardinia, Crete; NE, Finland, Russia, Chuvash; Ca, North Caucasus; CSE, Poland, Czech Republic, Romania, Bulgaria; NRE, Near East. Further details of samples are given in Table 1.
