What is a polygenic trait in humans?

  • Polygenic traits are traits that are controlled by multiple genes instead of just one.
  • The genes that control them may be located near each other or even on separate chromosomes.
  • Because multiple genes are involved, polygenic traits do not follow Mendel’s pattern of inheritance.
  • Instead of being measured discretely, they are often represented as a range of continuous variation.
  • Some examples of polygenic traits are height, skin color, eye color, and hair color.

Height

  • Human height is controlled by many genes, in fact, there are over 400 genes related to height, and all of these genes interact to make up a person’s phenotype.
  • This is a very large number, but it makes sense because height is a compilation of the lengths of many different body parts, such as leg bones, the torso, and even the neck.
