For each heteroplasmic female identified in the Line column, a sample of sibling females were split randomly into two groups, mated individually, placed at 18°C or 25°C, and allowed to lay eggs for >15 days. Each number indicates the proportion of long mtDNA within a single female fly. The U value is for the Mann–Whitney test between samples of siblings maintained at the two temperatures.
