For mars, they could do whole-genome sequencing and select for people with fewest deviations from the de facto wild-type human genome.
Comment on Why does incest result in birth defects?

Human genes only really “work” when they are combined from very different sets.
So-called “recessive” genes are overruled by your partner’s different pile of genes. They are usually shit traits like soggy bones or hair growing backwards, but since they never dominate, they haven’t been naturally selected away. They’re just harmless baggage.
You can still get them because it’s all random, but the likelihood is generally low.
If you don’t have that difference in mating genes, more of these recessive genes get to have a say in building the human. This severely increases the likelihood of birth defects.

That sounds unsettlingly like eugenics.

It’s 4 in the morning and I’m sick, got them albuterol inhaler shakes, and “soggy bones” made me laugh so hard I went into a coughing fit.

It was backwards hair that did it for me.
