Jul 28, 2017 at 18:51 | comment | added | Paul TIKI | @Draco18s still....eeeeeeeewwwwww :-P I know, hangups that the aliens may or may not have, but humans certainly do. Every culture I can think of has some sort of incest taboo. The familial distance may vary, but there always a point where they say "eeeeeewwwww" | |

Jul 28, 2017 at 13:07 | comment | added | Paul TIKI | @JBH but what about the...eeeewwwwww factor :) You may be right about the genetic diversity thing, but I would think that the closer the parity initially, the better off you would be if you are talking about a normal spread of potentially bad genetic markers. Now if your benevolent aliens screened for all those potentially bad genetic issues you could get away with a massive imbalance. | |
Jul 28, 2017 at 9:14 | comment | added | JBH | Genetic diversity would be basically met with 50 or so men. That's not actually a serious factor. The bigger one is how fast your ship of limited size can fill up. 50 men to 9,950 women (assuming our eager men are (ahem) up to the task) can maximally produce 9,950 babies every 9 months for a period up to, say, 10 years (eventually the woman's body gives out). That means in 5 years you have a maximum population of about 60,000 people... almost all of whom are under the age of 5. That means child care is a huge issue. Almost everything is more important to the scenario than genetics. | |
Jul 28, 2017 at 9:03 | comment | added | Mr Scapegrace | Fallout Bible mentions Vaults 68 and 69 with populations 999-1 and 1-999 male-female respectively. Let's just say that leaving 999 women with 1 man didn't end well. | |

Jul 27, 2017 at 22:31 | comment | added | Michael Morrison | Thank you for your excellent answer. Genetic disorders are a concern so your reply is helpful. Perhaps a starting population of 50,000 is more reasonable. How many men to insure sufficient generic diversity? | |
