Yes. Mice, fruit flies, plants, etc can be stably transformed so
that the recombinant DNA behaves as a simple Mendelian trait.
The recombinant DNA either segregates separately from the other
genes (as a plasmid or artificial chromosome) or is integrated
in the chromosome.
: in an evolutionarily stable manner.
That, of course, is a different fish -- whether the new material
confers a long-term advantage or disadvantage in the wild isn't
readily obvious. This is, of course, a significant concern --
it may not be desirable for human-modified species to survive
in the wild.
You could probably find a good article in Scientific American,
New Scientist, American Scientist, etc. by doing a literature
search for "transgenic".
