Genes are best defined as the units of heredity and biological traits. They are found on chromosomes in the form of DNA, which is a double helix molecule made up of four different nucleotides: adenine (A), thymine (T), cytosine (C) and guanine (G). Genes come together to form chromosomes that determine our physical characteristics, such as eye color. The more genes you have with one specific characteristic, the greater your chance will be for having that trait. For example, if you have two brown-eyed genes there’s an 80% chance you’ll also have brown eyes. A gene is best defined as the units of heredity and biological traits.
