Definition

A gene is a unit of genetic information passed from parents to children. Genes help determine traits such as eye color and also affect how living things grow and function.

Usage & Nuances

Usually used in biology, medicine, and everyday discussions about inherited traits: 'a gene for blue eyes', 'genetic gene mutation'. In casual speech, people also say 'It's in my genes' to mean a natural tendency inherited from family. Don't confuse 'gene' with 'DNA': a gene is a part of DNA.
