There's a new TV series that touches upon this - Orphan Black.

---- Spoilers, obviously ----

So they're clones, and they have a "special repeating marker" of some sorts. One of the clones is a biochemist, and she manages to decode it. Turns out, it is a copyright message covering those organisms and their biological offspring as property of X corporation. -------- Spooky, but wouldn't the message get diluted after reproduction?

From what I understand, the likelihood of any cistron in the genetic code getting diluted is dependent on the sequence length compared to the overall length of the chromosome on which it can be found.

However, since this is sci-fi, it may be possible that some of the genetic sequence is setup to actually alter the meiosis process and not perform any "crossing over" events in egg cell construction.
