Deletions and duplications in the mitochondrial genome. The coverage of the mitochondrial genome in five mutant strains is shown in a UCSC Genome Browser display, along with the gene content below. Although there are hundreds of copies of the mitochondrial genome in the zygote, both deletions (red bars) and duplications (green bars) were detected in the mutant strains. None of these were fixed in the strains, with both normal and altered length molecules detected in all cases.
