I have discovered a planet in the Wolf-359 system which is almost ideal for Human occupancy... a Nitrogen/Oxygen atmosphere which only needs a bit of Oxygen removed to drop it back into the habitable range. Temperature is OK (12 degrees C). The place even has a rich (multi-million ton, 0.8 concentration) deposit of the mineral that I require most urgently.
Unfortunately, the surface gravity is just a touch too high... just 0.03g above my tolerance range.
So I'm planning to breed a sub-race of "Heavies", to inhabit this new world. Obviously, only minimal Genetic Engineering will be required... a single tech will do it.
So I researched the +5% Gravity Biology tech (and the +10% Gravity tech for good measure), and I'm now researching the "New Species: Heavies" tech.
Question: How exactly do I create, segregate, load and ship these modified colonists?
I assume that once the New Species tech is ready, I will need to build a few Genetic Modification Centers on Earth, and set them to producing the new species. How will the modified colonists be seperated from the ordinary Humans? Will a new "colony" be automatically created on Earth for them? How do I make sure that my colony ship loads the modified colonists, and not ordinary Humans?
