Earlier quoted context omitted.
Zip is just a file format, it supports multiple compression algorithms. You can put any compression algorithm in a zip implementation. I mentioned it because it's the oldest and most well known. The parent would probably be best off using one of the specialty genomics compression tools, that's why I linked to them.
I thought ZIP files only supported a bunch of old algorithms like deflate. Maybe you can make an exotic zip file with zstd but doubt there are any tools that will understand it.
