How do polygenic traits work?
How do polygenic traits work?
Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Examples of human polygenic inheritance are height, skin color, eye color and weight.
Why is polygenic inheritance important?
Because of the inheritance mode patterns, the physical traits that are controlled by polygenic inheritance, such as hair color, height and skin color, as well as the non-visible traits such as blood pressure, intelligence, autism and longevity, occur on a continuous gradient, with many variations of quantifiable …
What are characteristics of polygenic traits?
Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.
Are polygenic traits affected by environment?
A polygenic trait is one whose phenotype is influenced by more than one gene. Traits that display a continuous distribution, such as height or skin color, are polygenic. Many polygenic traits are also influenced by the environment and are called multifactorial.
Is blood type polygenic inheritance?

Is color blindness a polygenic trait?
6 replies. “Definitely not monogenic, as there are multiple types of colorblindness (monochromatic, red-green, blue-yellow, etc.) that would be hard to explain with a single pair of genes. It is largely “”chromosomal”” as the affected genes occur on the X chromosome – which is why it’s most often seen in males.
