I was under the impression that anemones just split but I am by no means an expert.  I had a rose bubble tip who disappeared and now have about 20 baby nems in the tank.  One of these babies is about three times the size as the rest so I was thinking that was maybe the mama one.  Not sure but I know your guess is definitely better than mine.  I did not notice any eggy things on the bigger nem before the split, just FYI.
