 Defined as: manipulation involving taking genes from
their normal location in one organism and either
transferring them elsewhere or putting them back into
the original organism
 A part of Biotechnology
 American Association of the Advancement of Science
called genetic engineering one of the 4 major scientific
revolutions of this century.

the management of agricultural systems with an
emphasis on ecological and environmental
perspectives.
