Which is an example of a polygenic trait?

Some examples of polygenic traits are height, skin color, eye color, and hair color.

Which is an example of a polygenic trait quizlet?

Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of other animals. are those htraits that are controlled by more than one gene.

Is skin color a polygenic trait?

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.

How do you identify a polygenic trait?

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 eye color a multiple allele trait?

The best characterized example of multiple alleles in humans is the ABO blood groups, discussed in the Non-Mendelian Inheritance concept. Other human traits determined by multiple alleles would be hair color, hair texture, eye color, built, physical structures, etc.

What is the example of multiple alleles?

An excellent example of multiple allele inheritance is human blood type. Blood type exists as four possible phenotypes: A, B, AB, & O. There are 3 alleles for the gene that determines blood type. (Remember: You have just 2 of the 3 in your genotype — 1 from mom & 1 from dad).

What determines eye Colour?

Eye color is determined by variations in a person’s genes. Eye color is directly related to the amount and quality of melanin in the front layers of the iris. People with brown eyes have a large amount of melanin in the iris, while people with blue eyes have much less of this pigment.

What kind of trait is eye color?

polygenic

What is the best genotype?

Genotype Compatibility

Types of Genotype. The genotypes in humans are AA, AS, AC, SS. They refer to the hemoglobin gene constituents on the red blood cells.
Compatible genotypes for marriage are: AA marries an AA. That’s the best compatible.
Solution. The only thing that can change the genotype is the bone marrow transplant (BMT).

Is SC A blood type?

Summary. Hemoglobin SC disease, is a type of sickle cell disease, which means it affects the shape of the red blood cells . Red blood cells contain a protein called hemoglobin, which is responsible for carrying blood throughout the body.
