I'm going to throw out an off-the-cuff hypothesis. What about microchimerism as an inheritance process? Microchimerism is the presence of of cells that originate from another individual and are distinct from the cells of the host. Transmission between mother fetus has been observed. Moreover, olfactory bulbs are one area with continued adult neurogenesis. Thinking on that, I reasoned that if so, there might be increased neurogenesis in the olfactory bulbs during pregnancy in mice. A quick lit search came up with: https://www.ncbi.nlm.nih.gov/m/pubmed/12511652/ https://www.ncbi.nlm.nih.gov/m/pubmed/12511652/ Yes, increased neurogenesis during pregnancy in response to particular hormone. Pretty out there hypothesis, I know...

In the wrong direction (male fetus to mother, not sure they tested the other direction), but... http://onlinelibrary.wiley.com/doi/10.1634/stemcells.2004-0169/full http://onlinelibrary.wiley.com/doi/10.1634/stemcells.2004-01... "The male cells were found almost exclusively in Block 1, corresponding largely to the olfactory bulb." Now this is starting to be interesting!

Note that the “inheritance” can come from the father, and also happens with in vitro fertilization.

  Wow. Good point.

  Well it's also true that you can pick up cells from people you are genetically similar too and live in close proximity to. This might play a part in group cohesion?
