There are several terms for it.

I suspect it's more common than is generally recognized.

Thanks Rex.  You and Stathis identified it as heterozygote advantage.  I
thought there was a more specific term for that concept, but this states the
notion:

OK cool, so if we identify a bunch of these heterozygote advantages, then we
could use CRISPR to induce the mutant copy widely.  Then when couples with
the mutation mate, a heterozygous embryo is chosen, then the result is a
healthier population (even though not one which can reproduce haphazardly.)
