What about who are in the colony pods that are launched by colony ships?
End of BrotherBulger's quote
Nobody is in the colony pod... colony pod are big cloning machine who host a lot of various ADN sample...
These new way of colonize allow to have a fast growing population without the need of a huge colony ship... ADN sample don't need food or air during the transit and take very little place...
Once landed, engine of the colony pod are convert in a accelerated growing center who allow to have a fast increase rate of population... no more need to wait several generation sexual reproduction for only a light increase of population...
.....
It is sci-fi, simply use your own imagination and create your own story
