Genes are located on chromosomes, which are thread-like structures found within the nucleus of every cell.

Here's a breakdown:

* Nucleus: The control center of the cell.

* Chromosomes: Long strands of DNA (deoxyribonucleic acid) that contain genetic information.

* Genes: Segments of DNA that code for specific traits or characteristics.

Think of it like this:

* A book (chromosome) is made up of chapters (genes).

* Each chapter contains instructions for building a specific part of the body or controlling a particular function.

So, every gene has a specific location on a specific chromosome. This location is called a locus.
