What defines a transgenic organism?

A transgenic organism is specifically defined as one that has altered genes, particularly through the insertion of new genes that are typically sourced from a different species. This genetic modification is achieved using technologies such as recombinant DNA technology or gene editing techniques, allowing for the introduction of traits or characteristics that are not present in the original organism.

For instance, a plant that has been genetically modified to express a trait for resistance to pests by introducing a gene from a bacterium is a transgenic organism. This alteration not only modifies the existing genes but adds new genetic information that changes the organism’s traits and potential uses.

The other options do not accurately reflect the definition of a transgenic organism. Natural genetic variation refers to the differences that occur within species due to evolutionary processes, while losing genetic material does not pertain to the concept of transgenics. Being genetically identical to a parent refers to cloning or asexual reproduction, which does not involve the manipulation of genetic material to include foreign genes.
