Genes are biological units of the body which provide the directions for the body to function. They consist of Deoxyribonucleic acid (DNA) and determine an individual’s inherited traits.  For example, some genes are responsible for the colour of the eyes while others are responsible for the height of an individual.

Genes, being the building blocks of life, are also the basic units of heredity in living organisms.  It is the means by which all organisms pass on traits and attributes to their offspring.
