DNA polymerase is one of the methods used to carry out DNA repair. As it carries out replication it also carries out 'mismatch repair'. I'm not sure if this would be the type of repairing that would remove the navigator gene, it's just an example of DNA repair i know of.
To me, if you were to produce a slightly different polymerase via the aforementioned recessive gene you could control whether something was taken out of the DNA or left in.
DNA repair doesn't quite work like this. It repairs/corrects DNA on what it considers normal. This is in turn dependant on the inheritance from the parents. As such any traits inherited from the parents would be faithfully reproduced. As such the only way that a special case of "removes the navigator gene" would work is when there is another gene specifically (and artificially) encoded into the Navigator that prevents it from being removed in navigators, but whose absence allows it to be determined as foreign DNA by the body. Even this is a bit of pseudoscience, but it's not as if we're working with a hardcore science topic anyways.
Of course there is a simpler option. That when you mate a navigator and a normal human the offspring is infertile. That would probably satisfy GW's statement as well.
Now You're Talking. Of course it does mean that they are a distinct species and not really human anymore, but at least it's easier to justify.
Apology accepted, i know i offend people unknowingly via jest too so i can't really hold a grudge.
Great, it's all good then.
First off, be nice gentleman. We may be OffT but such is the way of the background threads. The only reason that a thread would be locked, or split and locked, is when people stop being nice. For those in need of inspiration, watch Roadhouse and the definition of "nice" in there!
Don't worry, we're all adults here. I come to 40k on-line to get away from the aggro of everyday life. As such I'm quick to apologise (although it does make me a bit snappy). Won't happen again (at least for a bit).
Assuming that they could maintain a breeding population. This is, of course, an assumption.
A reasonable assumption given some of my other points:
1) They are in high demand
2) They are elitist and stick to themselves (no watering down of the gene)
3) They are the most traveled class in the universe, so if a gene should be uniform, it would be theirs
4) Warp travel/ although dangerous, was not impossible, hence attrition, while high, could be easily countered.
Now these depend on how easily they reproduce, but it's not a stretch to say that they at least kept up with the attrition rates. If (Big if) this is the case, they would have been fairly common across the imperium and while not homogeneously distributed, would at least have been around on most of the larger/more civilised worlds.
Oh and by imperium and imperial space, I refer to the geographical area as opposed to the area bound under imperial rule.
They would have made warp travel much more managable...
I still feel that the second is assumption. Further, while I agree that Navigators would have survived in some parts of the galaxy, that such survival was heterogenous, not homogenous.
It's known for a fact that they make warp jumps easier etc, but I think your problem is not so much with that point rather than the fact that you think that this would have increased the attrition rather than lessened it (used on the more high risk routes/important missions etc). Please correct me if I'm wrong. Either way, while it is an assumption, I doubt that there would have been too much trouble with it.
On the whole homologous distribution issue, I'd believe that they were generally well distributed, with a few areas restricted (like Terra) from which he attrition rates where phenomenal. Apart from these areas the general warp could perhaps been even more stable than today (they only had 3/4 chaos gods back then, which begs me to ask why, oh why did they have all those problems back when slaanesh was asleep, but now that she's had her morning coffee, she's rather boring).
Another rather large assumption, though not necessarily unreasonable. Of course, it once again points out that the 'fluff' is inconsistent, since it would argue that every Forge world is the result of an Expeditionary Force sent out during the Age of Strife.
Well the assumption that they would have taken it into account is reasonable. Well, it's actually downright logical, but on the assumption that it would have worked is the big question here. Having the universe open at your door however and being able to suddenly receive the astropathical signals from everywhere would probably be a large incentive to believe them (also I'm sure a lot of these were fighting a battle of logistics and could have done with some outside help.)
The orks. Oh god.
I was merely referring to any alien race that popped into my head. Come on, how many other races that I didn't mention were really capable of starting their own Little empires?
Essentially the homogenous distribution of navigators, and the presence of the admechs have little to do with the topic or my post in general (the one that had everyone quote-warring).
Essentially all of my points indicated that the area that is now imperial space was made up of hundreds (or indeed thousands) of little "not-empires" (have to love turtledove's books). None of these would have obtained any real universal power (or the imperium would never have started) and they could have been made up of anything, orkses, hrud, jokearo, squat, humans, admech enclaves etc. Also Inside these not-empires there was most likely quite a bit of trade going (since their boundaries would have been mostly defined by the warp storms and other spacial obstacles). I'm willing to bet that they hardly knew of the other races/empires for the same reason.
I actually don't think that any of this is really that extreme or even a new idea. It just seems to be the best bet to what would fill the power vacuum. Or have I missed something?
