Which exception to Mendelism involves the expression of traits that are controlled by multiple genes?
The exception to Mendelism that involves the expression of traits controlled by multiple genes is called polygenic inheritance. In this type of inheritance, multiple genes contribute to the observable trait, and the trait often shows a continuous variation instead of distinct categories. Examples of polygenic traits include height, skin color, and intelligence.
How genes affect characteristics?
It is a polygenic character
Why is there a wide range of phenotypes in polygenic inheritance?
"polygenic inheritance"- the inheritance of quantitative traits, traits which are influenced by multiple genes. Polygenic inheritance shows how multiple genes in combination with a person's environment can influence someone's phenotype, or physical appearance. A wide range is produced because the gene combinations are vast.
When more than one pair of alleles controls a trait is called?
When more than one pair of alleles controls a trait, it is called polygenic inheritance. This means that multiple genes contribute to the expression of a trait, leading to a continuous range of variation rather than distinct categories. Examples of traits controlled by polygenic inheritance include height, skin color, and intelligence.
How are polygenetic traits inheritated?
Polygenic traits are controlled by multiple genes located on different chromosomes. Each gene contributes a small effect to the trait, resulting in a continuous range of phenotypes. The inheritance of polygenic traits follows the principles of Mendelian genetics, with the combined effect of multiple genes influencing the trait's expression in an individual.
What ar human traits controlled by?
polygenic inheritance

What is Polygenic Inheritence?
Polygenic inheritance refers to the inheritance of a trait that is controlled by multiple genes, each with a small effect on the phenotype. Traits such as height, skin color, and intelligence are often influenced by multiple genes working together. This type of inheritance results in a continuous range of phenotypes rather than distinct categories.
Many human traits such as eye color and height are controlled by?
Polygenic Inheritance
How inheritance by multiple alleles and polygenic inheritance are similar?
I think that , they r both controlled by more then 2 allels.
What are the differences between epistasis and polygenic inheritance in terms of their impact on the expression of traits?
Epistasis occurs when one gene masks the expression of another gene, leading to a specific trait being completely hidden. Polygenic inheritance involves multiple genes contributing to a trait, resulting in a more continuous range of expression. Epistasis has a more direct and immediate impact on trait expression, while polygenic inheritance leads to a more gradual and varied expression of traits.
What is trait called when it is controlled by more than one gene?
Polygenic Traits
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.
How genes affect characteristics?
It is a polygenic character
Are all characteristics controlled by only 1 gene?
No, characteristics can be controlled by multiple genes interacting with each other. This is known as polygenic inheritance. Additionally, environmental factors can also influence the expression of these genes, further complicating the determination of specific genetic control.
Why is there a wide range of phenotypes in polygenic inheritance?
"polygenic inheritance"- the inheritance of quantitative traits, traits which are influenced by multiple genes. Polygenic inheritance shows how multiple genes in combination with a person's environment can influence someone's phenotype, or physical appearance. A wide range is produced because the gene combinations are vast.
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.
