number of women vs. men,
Isn’t this statement bigoted against the LGBT peoples???
This is hetero normative, and binary, in their assessment of sexual ratios, sexual reproduction, etc. What if there are disproportionate numbers of “gay” peoples or “transsexual” peoples who will be axed out of the reproductive cycles?

They have to think through many many factors.
Suppose they arrive at Promixa Centauri, and find there are no earth like planets on which to settle? Then what?
Imprisoned women breeders artificially inseminated for the gay overmasters. Strange things could develop on a generational ship in 6000 years. Or at least that’s what sci-fi says.

Read Larry Niven’s Known Space collection of books. The probes sent from Earth were badly programmed...and yes, the generation ships had it rough when they got there.
