Genes are segments of DNA that contain instructions for building and maintaining an organism. They are essentially blueprints for life.
However, people sometimes use the term "gene" loosely, referring to organisms themselves. For example, someone might say "a new gene was discovered in humans" when they really mean "a new gene was discovered in the human genome."
So, to answer your question directly:
* Genes don't call humans anything because they are not sentient beings.
* Humans, however, study and name genes. We identify them based on their function or location on the DNA strand.
