| Apr 13, 2017 at 9:24 | comment | added | DRF | @jean How many kids have you had? The idea that relationships and breeding can be unrelated seems extremely unlikely to me. The reproductive imperative is far too ingrained to just be societal pressures IMO. | |
| Oct 22, 2015 at 17:46 | comment | added | jean | For a interestellar spaceship I guess the best approach is to send female only embrios and lots of sperm (bonus: human bodys cannot sustain too much acceleraiton). Defroze the first female generation just a few years before arriving. Males are not really necessary in the first generations and a unique male can let lots of females pregnat. Free of actual society vices and relogious/constumary rules and taboos breeding and raising humans cannot be a problem at all. It can be done in a collective way without pressures, like realtionships and breeding become total unrelated | |

Therefore, some of the sperm would have to male. Moreover, you'd want a backup so live men would be the best choice. In theory, since sperm are generated outside the primary immune system, you could transplant the sperm stem cells of many men into one, turning that one guy into say 50 genetic individuals. | |
| Oct 8, 2014 at 18:20 | comment | added | Octopus | Men aren't necessary at all in a scenario like this. All the genetic material could be gathered from two eggs and in vitro fertilization. There would be no y chromosomes and therefore never any boys would be born. | |
| Oct 8, 2014 at 8:50 | comment | added | celtschk | Good points. Indeed, it would even be conceivable that after the first colonists, only sperms are sent up in order to provide genetic variety. That would be much more cost-effective since the further ships would not need life-support systems. | |
