i would like to point out that not a single chapter has a completely stable gene-seed. the ultramarines' gene-seed is indeed one of the most stable, but mutation of the gene-seed, however slight it may be, does occur. for example - dark angel gene-seed is the single most stable of any chapter, and yet even this has mutated, again it's a slight mutation, from what it originally was.
