The instructions for traits that are passed from parents to offspring are known as genes.

Here's a breakdown:

* Genes: Segments of DNA that contain the code for specific traits.

* DNA: The molecule that carries genetic information.

* Traits: Characteristics or features of an organism (e.g., eye color, height, hair color).

So, genes act like blueprints, providing the instructions for building and maintaining an organism, and these instructions are passed down through generations.
