Ok, so before you guys look at me crazy, this is research for some leisure sci-fi writing...
Where do we get our microbiota from?
Like, obviously test tube babies have microbiota too, how do they get them?
Do people with relatively large genetic variation exhibit noticeable differences in their microbiota composition?
Do people that live in different geographic areas exhibit noticeable differences in their microbiota?
If you swapped all my microbiota with someone else's, whom is vastly different from myself (but same sex), would we live?
