It doesn't matter, because almost certainly this setup will fail.
as other users have said, a new colony needs A LOT of work, and you cant really automate all of it, especially not for the first years. think about it the new location might not be good for farming, or might not be good for farming what you have, and you need farming sorted out fast, and remember, almost all the humans are busy, the women with presumably caring for their kids, the men could farm, but there's no way they could farm enough, they don't have the resources, remember the land where they are is pretty unknown. Aside from that who is gonna be teaching and caring, it can't just be the parents, they couldn't do it and if you want the teens to do it, well they wont do a good job because pretty soon your gonna have problems with education. if you have an automated education system, who is gonna do maintenance on any of the systems? you don't have many spare people so soon stuff is gonna break down and you won't have anyone to fix it.
let's say all that gets figured out somehow. 998
Your colony will grow fast. After just 2-3 generations, you will be having in the hundred thousands, and those people need houses, your gonna need to find a way to make those houses, (remember the humans can't do that)
let's say you still get that automated. people are eventually gonna want rights, so they will revolt, but against who? that brings another problem, who is controlling this all? in short, i think you need to tweak the numbers a bit, and change how its structured to get a working colony that CAN grow.
How to fix those
First off, you need to make the growth smaller so the colony can keep up better, 100 kids per guy and 12 kids per gal is a very large number, especially in an unexplored environment, resources wouldn't keep up well, and care would be difficult otherwise, using half that would probably fix both. (edit it has come to my attention that only 25 kids would be genetic at all for fathers, for a few generations at least, you cant keep splitting them forever, and with growth there wont be enough to spread out to everyone, so that number will increase eventually)
Next, you need to probably need to rethink having males never get into harms way like you say, if you want them to do work that has to get done, they are gonna be in harms way, and if you did step one, then they could get hurt more, and each have a tad higher number than the half you just mad them have.
You can adjust a bit of what i suggest to better fit your likings but i dont think your current setup will work as well as you hope 998
