Vinny, in ALL CASES fruit will come from every tree planted by seed. There are many types of mandarins, so what you purchased could be anything. I plant clementine seed BECAUSE they produce fruit that don't come true from seed. Each seed will produce a one of a kind never seen before citrus fruit. The fruit might be better than the mother, inferior to the mother, and many times pretty much the same as the mother fruit. Most all mandarins produce fruit true from seed with the exception of Clementine and King, also Temple Tangor and pummelos do not produce true. - Millet
