Eye color is a polygenic trait. Height and skin color are also polygenic traits. If there is a vast variation in a trait, it's likely that it is polygenic.
Polygenic traits are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of oth
Examples of polygenic inheritance in humans include height, eye color and skin color. Physical traits that have polygenic inheritance are influenced by more than one gene and typically display a continuous distribution, such as a range of heights. Polygenic traits do not have the classic phenotypic

A polygenic risk score tells you how a person’s risk compares to others with a different genetic constitution. However, polygenic scores do not provide a baseline or timeframe for the progression of a disease. For example, consider two people with high polygenic risk scores for having coronary heart disease. The first person is 22 years old ...

Coronary artery disease (CAD) is the leading global cause of mortality and has substantial heritability with a polygenic architecture. Recent approaches of risk prediction were based on polygenic risk scores (PRS) not taking possible nonlinear effects into account and restricted in that they focused on genetic loci associated with CAD, only.
The application of polygenic risk scores (PRS) has become routine in genetic epidemiological studies. Among a range of applications, PRS are commonly used to assess shared aetiology among ...
