What terms describes natural selection that acts against intermediate forms of a polygenic trait to increase genetic variation while not changing the average value of a trait within?
Disruptive selection
What is the genetic composition determining a trait?
Genotype is the genetic makeup of a trait.
What makes something a sex-linked trait instead of just a regular trait?
A sex linked trait can only be found on the x chromosome such as hemophilia, color blindness, and muscular dystrophy. These are traits that can only be inherited through chromosomes instead of regular traits coming through genes.
Would a disease caused by exposure to chemicals be considered a genetic trait?
A genetic trait is passed on through the genes. Which means that disease from exposure to chemicals is not inherited.
What is a contrasting trait?
pea has many sharply ditinct traits each trait has two clear alternative forms e.gseed shap has round or wrinkled phenotype plant hieght was long or short seed colour was yellow or green Mendel called them pair of contrasting trait
True or false height is not a polygenic trait?
false, height is a polygenic trait
Why is height considered a polygenic trait?
Height in considered a polygenic trait because your height is influenced by multiple genes.
In a species of rat height is a polygenic trait. what does it mean for this trait to be polygenic?
Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be of 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. Should help students for the year 2022. (Note: May change for upcoming years) Hope it helped!
Are Human traits like eye color and height inherited by polygenic traits?
Human eye color is an inherited polygenic trait because it is controlled by more than one gene. Various eye color includes blue, green, amber, hazel, brown, and violet.
What type two or more genes control a trait?
Polygenic trait
How many genes determine an inherited trait?
Hello there! Traits controlled by two or more genes are for example skin color and height.
What is is a polygenetic trait?
A collection of paired genes is responsible for a polygenetic trait. Height, skin colour etc. are examples.
When a trait has more than two alleles how is the trait inherited?
When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance. Many quantitative characters have polygenic inheritance. Inheritance of blood groups is an example of polygenic inheritance in human being.When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance.

What controls a polygenic trait?
two or more genes
What is the interactive nature of polygenic genes?
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.
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
What is a trait said to be when several genes influence it?
the answer is polygenic
