Forty-six pedigrees relating sampled individuals. Individuals represented by filled black squares and circles were analyzed in the first step; those represented by half tone squares and circles were analyzed after detection of heteroplasmy in individuals analyzed in the first step; samples of individuals represented by grille squares and circles were available but were not analyzed; samples of individuals represented by white squares and circles were not available. In all cases heteroplasmy is signaled with arrows.
