[QUOTE="Tonguez, post: 7555710, member: 1125"] The calculation has been done by the University of Florida for a space trip of 200 years, (eight to 10 generations) and suggest a minimum number of 160 people are needed to maintain a stable population Apparently that yields 10 potential partners per person and avoids both inbreeding and genetic drift. However the study also suggest that the number could be halved to 80 if women are asked to wait until after 35 before having children (this increases the gap between generations but increases medical risk from pregnancy) All crew members would also need to be genetically screened prior to inclusion to ensure no unwanted recessive factors affecting future population health. The other big issue raised by the study was Infighting which rises in small isolated communities with no way to get 'out' - if one person does wrong how does the community survive any potential conflict and faction-forming meat can be grown from real animal cells and fortified with b-vitamins, so as long as they have a viable source of animal cells preserved then they can keep growing viable meat (lets ignore the likely soylent developments) Having a beehive colony on board might be an option for both pollination of crops, honey and 'meat', I wonder too if worms or even microbial sources could be used to develop meat alternatives (apparently the Kombucha scoby is edible though I've never tried it).
