> undiscovered checksum scheme

I don't think checksum is a fair metaphor for anything happening in biological systems.

> Most mtDNA between humans is the same

And most DNA is also the same. A percent difference is the kind of thing that would require millions of years of divergence to develop.

> mtDNA is only 16,569 base pairs long

This is really not so precise. There will be a mixture of lengths due to insertions and deletions, even in the same individual, even in the same cell.

> The differences between mother and child are almost always due to the father's contribution, and not to mutations.

Do you have a citation for this?

The number of base pairs in human mtDNA is not a subject of scientific ignorance nor of dispute; it has been known for decades. [1] This kind of objection is unproductive, and indicates one may benefit from personal study of the subject instead of arbitrarily casting doubt.

Checksum is a solid analogy, take natural abortion. If a fetus fails specific challenges it’s removed. This is very common, with a significant portion of pregnancy’s ending this way.
