Is there such a thing as genetic memory?

Is there any science behind genetic memory, a la Dune?  
Is it possible that "information" is passed to the fetus from the mother during pregnancy?

Short answer: not in anything like the way you're thinking, no.

Slightly longer answer: first of all, the only truly genetic information the fetus gets from its mother is in the DNA of the egg, which actually forms while *she's* still in her mother's womb - she just has one batch of oocytes for her whole life that she doles out one by on for a few decades. She could get cancerous mutations all over her body, but they wouldn't be inherited because they wouldn't affect the DNA in the oocytes. 

Now, there are some known ways that information from the mother's womb can leave an imprint on the fetus for the rest of its life, even though they're not strictly genetic. It's starting to look like intrauterine environmental stimuli like hormone levels and food shortages can cause permanent epigenetic modifications to the fetus' DNA that will change its hormone responses or metabolism long into its adult life. If you want to consider this information transfer from the mother, that's not wrong - it's just not genetic, not information passing from her genome into the fetus' genome.
