Refers to each instance of a genetically engineered organism. For example, the same gene inserted by man into a given plant genome at two different locations (i.e., loci) along that plant’s DNA would be considered two different “events.” Alternatively, two different genes inserted into the same locus of two same-species plants would also be considered two different “events.” Generally speaking, the world’s regulatory agencies confer new biotech-derived product approvals in terms of events.
In the PERT network, events are the completions of major product tasks.
