Which statement best describes a transgenic organism? 

A)  An organism that is the result of traditional crossbreeding of two species. 
B)  An organism that has both male and female characteristics. 
C)  An organism that contains genes from a totally genetically unrelated species. 
D)  An organism that is the result of artificial selection of two closely genetically related species.

A transgenic organism is defined as an organism that has had genes or DNA from an unrelated species artificially introduced into their genetic makeup. This is often done using genetic engineering techniques, such as gene splicing or recombinant DNA technology. Option A refers to traditional crossbreeding, which does not involve the introduction of genes from unrelated species. Option B refers to hermaphroditic organisms, which have both male and female reproductive organs, but this does not relate to the definition of transgenic organisms. Option D refers to artificial selection, which involves selective breeding of individuals from the same species within a population to produce desired traits, but this does not relate to the definition of transgenic organisms which require genetic engineering.
