you mean to say that they would procreate in the same way that normal humans do, by mixing dna of 2 specimen, instead of reapplying one set of genetic material to new aspirants

aka a load of the time the gene-ssed spends in cryogenic stasis, not changing, and at other times, it is maturing inside a marine, meaning that the rates of mutation and adaptatrion are a lot slower on them, hence also the low mutation on the gene seed of all 1st founding templates that do not spend time in the warp for prolonged time or are experimented upon by the mechanicum

but meh let's go into canon information ;) bloodangels still have all organs functioning in their gene seed (5th ed bloodangels codex) dark angels: no information either here or in lexicanum raven guard: 1 organ not functioning, melanchromatic mutated though theory: corax modified the gene-seed, is that his fault, or time? salamanders: all organs present, only melanchrome organ changed ( see black primarch) iron hands: no flaws imperial fists: lost 2 organs, however source of that is the non canon source "space marine" ultramarines: all organs present according to sources space wolves: no history of missing organs or anyhting like that

so basiccally 7 of 9 first founding legions still have all organs/stable gene-seed  one was worked on by their own primarch, unknown wether that had effects, the other only lists non canon source  (though i might have to get some imp fist stories to get more info there)

amusing.. what was the mutation rate again?
