For the amount of volume/mass required to ship a single human and support them in transit and on site you could ship a lot of embryos in cryo(it's careful plumbing; but a big dewar flask kept at cryogenic temperatures is downright lightweight compared to a full life support system); and shipping embryos gives you the option of bringing massive genetic diversity, thousands to tens of thousands of genetically screened parents worth of embryos in the space a single person would require.
Unless you've got some sort of advanced growth vats you would obviously need people onsite; but instead of dealing with the probably-impossible task of keeping a tiny breeding population's gene pool in order you'd just be defrosting and gestating specimens from a much larger pool of diverse embryos as needed. Presumably you'd initially go with an all-female colony, and only start defrosting males and trying to maintain a viable natural population once you had at least high single-digit thousands to low-mid tens of thousands.
I'm sure that such an arrangement would freak some people out; and you'd probably need to do some reasonably intense social engineering to keep everyone on-mission; but in terms of efficiency of genetic diversity there's a fairly compelling case to be made.
