In my most recent story, the aliens have built a generation ship for humans to travel on. These humans are traveling to a planet that has dinosaurs originally from earth that survived as species. The planet itself is 200 light years away and the ship is traveling at .5 C. I have designed it so that each generation can only reproduce after they have went through survival training. This comes after basic training(from toddlers to adults). The aliens themselves run on specific protocols and to them they are needed laws. To the humans, the protocols are unnecessary and wrong. Now after survival training, any remaining males and females of reproductive age are randomly paired up and then in the second sleeping quarters(there are 2 of them for humans and 1 for aliens) they mate and sleep throughout the day and night(diurnal: mate during day, sleep at night, nocturnal: sleep during day, mate at night) Now they make sure that they never have a diurnal x nocturnal pair to make things easier for all humans and aliens. A week later, the aliens take all the mated females and use an endoscope/microscope to see the egg and whether or not it is developing properly. They terminate the pregnancy only if: 1) it is ectopic Or 2) it isn't developing properly in the embryonic stage Basically they induce a miscarriage in either of these circumstances if possible and if that doesn't work, they do surgery, again with super small tools to minimize damage to the mother. Now the pregnant females are taught about pregnancy and what to expect. This is important because, most likely some pregnant women will be cryopreserved near the end of the trip. Anyway I have some questions about this. 1) If human A develops a natural antivenom to a particular animal and is pregnant, will that antivenom be passed on to the baby? 2) Should the humans follow the aliens' protocols or do things when they want to as long as it isn't harmful? 3) Should they have a second round of mating a month later for any non-pregnant females of reproductive age but this time with different males or multiple males mating? 4) Is survival training really needed for every generation in 400 years of space travel? 5) The lecturing room is already very flexible but should it be the humans and not the aliens that decide on the courses? 6) Should survival training include everything from quicksand and first aid to croc and shark attacks(not with real animals of course) and a T rex attack being the ultimate survival challenge? 7) Should some aliens go through the same mating and pregnancy process as the humans and support them through it with their own pregnancy knowledge?
