What is the term used to refer to an organism that contains genes from other organisms?

The term that refers to an organism containing genes from other organisms is "transgenic." Transgenic organisms are created through genetic engineering, where DNA from one species is inserted into the genome of another species. This manipulation allows the transgenic organism to express traits that are not naturally its own, resulting in various applications, such as improved agricultural yields or the production of pharmaceuticals.

While "genetically modified organism" (GMO) is a broad term that encompasses any organism whose genetic material has been altered using biotechnology, not all GMOs are necessarily transgenic. Some may involve gene editing or other forms of genetic alteration that do not involve transferring genes between different species.

The term "cloned organism" specifically refers to organisms that are genetically identical copies of another organism, which does not necessarily involve the insertion of foreign genes. Similarly, a "synthetic organism" typically describes organisms that are constructed from scratch, using synthetic biology techniques, which may or may not involve the incorporation of genes from other species.

By focusing on transgenic organisms, you recognize the specific context of genetic engineering with foreign gene incorporation, which directly addresses the question asked.
