Here's a breakdown:
* Genes: These are the basic units of heredity. They contain the instructions for building and maintaining an organism.
* Chromosomes: These are long, thread-like structures made of DNA and proteins that carry genes. Humans have 23 pairs of chromosomes, with one chromosome from each pair coming from the mother and one from the father.
* Traits: These are the characteristics that are passed down from parents to offspring, such as eye color, hair color, and height.
So, genes are the specific segments of DNA on chromosomes that are responsible for the inheritance of traits.
