I don't remember the thread in question, so I may not have found the right info, but here is a section from Wikipedia:
quote:The story shares parallels with Robert Heinlein's 1942 novel Beyond This Horizon. In that story, doctors would design each child by selecting the best of the parents' genes; using genes not found in either parent was forbidden. As in Gattaca, people without engineered genomes were looked down upon. Another similarity between Gattaca and Heinlein's writing is that the protagonists in both Gattaca and Heinlein's story Starman Jones memorize a book on interstellar travel and falsify their identities in order to gain employment.
