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

Polygenic inheritance is the inheritance of traits such as skin color, eye color, and hair color, that are determined by more than one gene. Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. These genes, called polygenes, produce specific traits whe
In genetics, a polygenic score, also called a polygenic risk score (PRS), genetic risk score, or genome-wide score, is a number that summarises the estimated effect of many genetic variants on an individual's phenotype, typically calculated as a weighted sum of trait-associated alleles. It reflects an individuals estimated genetic predisposition for a given trait and can be used as a predictor...
However, Mavaddat et al. show that PRS is informative in stratifying risk, with the 20% of women with the highest polygenic risk scores reaching this level of risk before age 40 and the 20% of women with the lowest scores never reaching this level of risk. This study shows that breast cancer polygenic risk scores already capture sufficient ...
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 ...
Polygenic risk scores (PRS) are on course to translate the results of genome-wide association studies (GWAS) into clinical practice. To date, most GWAS have been based on individuals of European-ancestry, meaning that the utility of PRS for non-European populations is limited because SNP effects and LD patterns may not be conserved across populations.
But a growing number of DNA experts believe using polygenic information through polygenic risk scores (PRS) is the wave of the future. However, just as in 2000, there's a scientific “hodgepodge ...
