Height is a phenotype, an observable trait of the genes that we inherit from our parents. It's a polygenic trait, meaning it is controlled by 2 or more genes. Because it is so easy to measure, it is an ideal characteristic to help us understand other polygenic traits. So far, genome-wide association studies (GWAS) have identified 700 common variants that determine a person's height. New discoveries have been made by the international group called Genetic Investigation of Anthropometric Traits (GIANT), revealing 83 genetic mutations that have additional effects on a person's height.1
