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. Polygenes exist in other organisms, as well.

Traits controlled by two or more genes are called what?
Traits controlled by two or more genes are called polygenic traits. In polygenic inheritance, multiple genes work together to produce a particular phenotype, resulting in a wide range of possible variations. Examples include height, skin color, and eye color in humans.
What type two or more genes control a trait?
Polygenic inheritance is when two or more genes interact to control a trait. Each gene contributes to the phenotype in an additive manner, resulting in a continuous range of variations for the trait. Examples include human height and skin color.
How are the word parts poly- and genic related to the meaning of the term polygenic traits?
The word part poly- means "many," and genic refers to genes. Polygenic traits are determined by multiple genes, each contributing a small effect to the overall trait. So, the terms poly- and genic in polygenic traits indicate that multiple genes are involved in determining the trait.
What is the difference between epistasis and polygenic inheritance in genetics?
Epistasis is when one gene affects the expression of another gene, while polygenic inheritance involves multiple genes contributing to a single trait. Epistasis involves the interaction between genes, while polygenic inheritance involves the cumulative effect of multiple genes on a trait.
What is the opposite of polygenic trais?
The opposite of polygenic traits is monogenic traits. Polygenic traits are determined by the interaction of multiple genes, while monogenic traits are controlled by a single gene.
Are polygenic genes dominant genes?
Polygenic genes are usually dominant genes.
How genes affect characteristics?
It is a polygenic character
Traits that are shaped by many genes are called what?
Traits that are produced by the interaction of several genes are called polygenic traits. Examples of polygenic traits are height and skin color.
What controls a polygenic trait?
two or more genes
Traits controlled by two or more genes are called what?
Traits controlled by two or more genes are called polygenic traits. In polygenic inheritance, multiple genes work together to produce a particular phenotype, resulting in a wide range of possible variations. Examples include height, skin color, and eye color in humans.
Traits that are produced by the interactions of several genes?
polygenic
What is a trait or genetic disorder caused by Polygenic inheritance?
A polygenic trait is a trait which multiple genes affect. An example would be skin color, the combined affects of several genes determine your base pigment shade. Polygenic traits are caused by a combination of genes.
Why is height considered a polygenic trait?
Height in considered a polygenic trait because your height is influenced by multiple genes.
What type two or more genes control a trait?
Polygenic inheritance is when two or more genes interact to control a trait. Each gene contributes to the phenotype in an additive manner, resulting in a continuous range of variations for the trait. Examples include human height and skin color.
What traits that are caused by the interaction of the many genes said to be?
polygenic
What are the characteristics of polygenic traits?
Polygenic traits are determined by the interaction of multiple genes, each contributing a small effect towards the phenotype. They often display a continuous range of phenotypes rather than distinct categories. Polygenic traits are influenced by both genetic and environmental factors.
What is the opposite of polygenic trais?
The opposite of polygenic traits is monogenic traits. Polygenic traits are determined by the interaction of multiple genes, while monogenic traits are controlled by a single gene.
