What is a polygenic trait for kids?
A polygenic trait is a characteristic, such as height or skin color, that is influenced by two or more genes. Because multiple genes are involved, polygenic traits do not follow the patterns of Mendelian inheritance. Many polygenic traits are also influenced by the environment and are called multifactorial.
What is a polygenic trait explain with an example?
Polygenic Inheritance Examples Skin pigmentation: inheritance of skin pigmentation is polygenic inheritance. Around 60 loci contribute to the inheritance of a single trait. If we take an example of a pair of alleles of three different and unlinked loci as A and a, B and b, C and c.
What are some examples of polygenic inheritance?
What are polygenic inheritance examples? Human phenotypes or human physical traits such as hair color, height, skin color, blood pressure, intelligence, autism, and longevity are some of the examples of polygenic inheritance.
How can you tell if a trait is polygenic?
Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall.
Is hair color a polygenic trait?
Human skin, hair, and eye color are also polygenic traits because they are influenced by more than one allele at different loci.

Why are polygenic traits important?
The statistical analysis of polygenic inheritance patterns can help to provide an estimate of population parameters. Most of the polygenic inheritance follow the normal distribution curve, wherein the majority of the people fall in the middle range of the curve. Polygenic inheritance is different from multiple alleles.
Which definition best describes polygenic traits?
The best definition which describes polygenic traits is : B) traits that are controlled by multiple genes. Polygenic traits basically mean the traits that are a result of multiple intertwined traits like for example skin colour.
