Definition for Determination
From Biology Forums Dictionary
1) In developmental biology, determination is the early commitment of a cell to an eventual developmental fate.
2) The determination of different cell types (cell fates) involves progressive restrictions in their developmental potentials. When a cell “chooses” a particular fate, it is said to be determined, although it still "looks" just like its undetermined neighbors. Determination implies a stable change - the fate of determined cells does not change.
