Odds are it probably will not be tasty, that's what I'm trying to tell you. If people could get tasty figs from just planting seeds then everybody would be doing it. A desirable fig from seed is a rare thing. It takes several years for a fig tree to produce figs from seed, if it produces them at all. The only people who benefit from fig seeds are the ebay sellers who sell them to unknowing people, except for the plant researchers/breeders who have the funding, time and resources needed to carry seed plants to fruition.
Your dad said no more plants right? I doubt he would like all those probably worthless seedlings stacked up everywhere. :)
For an eleven year old, you certainly have a lot of knowledge. When I was eleven...wait, I can't remember that far back lol.
