We know that every gene seed is NOT unique, as some chapters are second founding and so on and so forth of the initial legions. Ergo they will have the same genetic material of their parent chapter/legion. I would however propose the this will be fairly neutral, so as not to bring genetic shift into the newer units.

The Grey Knights are post Horus so the variance will have likely increased dramatically in the last 10,000 or so.

You would always be able to trace a genetic history of a marine/person. That's done ofte enough now. Read up on the Human Genome Project if bored.

Am I the only one who is struggling to work out what f.e. actually is?
