Hi, as title says. Seeing how the the gene seed are supposed to be tested regularly by the admech for mutation / chaos corruption, shouldn't it be super easy to run a quick analysis from a gene seed dna sample to and get a match that way ?

I get that 10000 years is a long time, but some dna material from the primarchs has to still be in there for the space marine making process to work right ? For the same reason the blood angels successor chapters still have the red thirst inherited from sanguinus.

Thanks!
