What is the relationship between a genome, chromosomes, and genes?

Genome, chromosomes, and genes are all different DNA structures related to each other.

Explanation:

The genome is the set of hereditary material of an organism, the sequence of nucleotides that specify the genetic instructions for its development and functioning and that are transmitted from generation to generation, from parents to children.

The genome is organized into chromosomes, chromosomes are X-shaped supercoiled DNA structures. Each species has a characteristic number of chromosomes. In the human species each somatic cell has 22 pairs of autosomal chromosomes and one pair of sexual chromosomes (X and Y).

A gene is a unit of DNA information that encodes a functional product, such as proteins. Genes represent approximately 1.5% of the genome. Each gene have a location within the chromosomes called locus.
