Sentences with phrase «single gene»

The phrase "single gene" refers to a specific section of DNA that contains the instructions for making a particular characteristic or trait in a living organism. It means that this specific gene is responsible for influencing one specific thing about an organism, such as its eye color or the production of a certain protein. Full definition
