After some testing I've noticed that there's not just one single pollination technician per save file, there are several, BUT they're all named Pollination Technician #3. I had a sim get pregnant by abduction three times, and the babies were tagged as half-siblings with each other, and when looking in the genealogy I can see that they have different mothers with different faces (though all of them were blue, but I think that might've been by chance).
Anyway, I think the pollination technicians should be premades, and one of each alien skin tone, to avoid getting all in-game born aliens having the same skin tone by chance (it's not like there are a lot of in-game born aliens happening anyway, a bit of diversity doesn't hurt).
I also think that not only should there be settings to avoid pregnancy from abduction altogether (in the save file settings) but there need to be some kind of alien pregnancy settings in CAS, because it's impossible to have a male sim in the science career without him getting impregnated by aliens over and over again, and it's still a problem with in-game born male aliens having the chance of getting impregnated by their own mother, that has to be fixed in some way.
