Genes are segments of deoxyribonucleic acid DNA that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are made of a very long strand of DNA and contain many genes hundreds to thousands. Except for certain cells for example, sperm and egg cells , every human cell contains 23 pairs of chromosomes. There are 22 pairs of nonsex autosomal chromosomes and one pair of sex chromosomes, for a total of 46 chromosomes.

On the other hand, it can also refer to one or a set of genes or a combination of alleles or haplotypes, which are groups of genes that are inherited together carried by an individual.
