If I cross-pollinated a Sitrus Berry and a Lum Berry, can the resulting Tamato Berry be used to get more Tamato Berries? I know the answer is probably yes, but I want confirmation.
Yes, a mutated berry (as an item in it self) is no differen from other berries, so you could replant the Tamato berry to get a Tamato berry tree.
Source - logic and doing this more than once.
