The presence of over 700 genes involved in height determination is an example of a polygenic trait.
<h3>What is a polygenic trait?</h3>
A polygenic trait refers to a trait that is determined by multiple genes rather than by only one gene. This is opposite to a monogenic trait that is determined by only one gene.
<h3>What are some examples of polygenic traits?</h3>
In humans, some examples of traits that are determined by multiple genes are:
- Height
- Hair color
- Skin color
