I don't think this is too big a problem because transgenes are spliced onto
a promoter that turns them on in a particular tissue. There are not very
many promoters in use. The promoter sequences can apparently be used as PCR
primers in a cocktail to generically detect GMO's with great sensitivity (I
would say excessive sensitivity!).

The assumption of independent assortment is not really very good over time
scales of cultivar development, and chunks of chromosomes are inherited. It
is possible to trace the heritage of genetic material that has been stolen,
even without distinctive promoter sequences. Pioneer has half the corn seed
industry in court right now, and they have had to admit chasing selfs in our

All the information about promoter sequences, and transgenes in general is
patented and in the public domain. Developing these things is a big deal,
and there is great incentive to patent everything.
