A funny study in PNAS is broadening our view of paranormal inheritance by showing germline chimerism in marmosets:

Using microsatellite DNA markers, we show here that chimerism in marmoset (Callithrix kuhlii) twin … somatic tissue .. found to be chimeric. Notably, chimerism was demonstrated to be present in germ-line tissues, an event never before documented as naturally occurring in a primate. In fact, we found that chimeric marmosets often transmit sibling alleles acquired in utero to their own offspring.
