How can mitophagy be an effective quality control mechanism if mtDNA mutations reach high enough levels to cause disease?

This question led us into a dark path, full of concepts of evolutionary genetics, germline stem cell biology and mito-nuclear compatibility.

Ubiquitin-mediated mitophagy regulates the inheritance of mitochondrial DNA mutations

Mitochondrial synthesis of adenosine triphosphate is essential for eukaryotic life but is dependent on the cooperation of two genomes: nuclear and mitochondrial DNA (mtDNA). mtDNA mutates ~15 times as...
