1) Organisms that have had genes from other species inserted into their genome.

2) One into which a cloned genetic material has been experimentally transferred, a subset of these foreign gene express themselves in their offspring.

3) Transgenic means that one or more DNA sequences from another species have been introduced by artificial means. Animals usually are made transgenic by having a small sequence of foreign DNA injected into a fertilised egg or developing embryo. Transgenic plants can be made by introducing foreign DNA into a variety of different tissues.
