What is an example of a polygenic trait?

A polygenic trait is a characteristic, sometimes we call them phenotypes, that are affected by many, many different genes. A classic example of this would be height. Height in humans is very strongly genetically controlled, but there are many, many different genes that control height.

What is a polygenic trait List 3 examples?

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

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. Such traits may even be controlled by genes located on entirely different chromosomes.

What characteristics are polygenic?

Polygenic traits have a bell-shaped distribution in a population with most individuals inheriting various combinations of alleles and falling within the middle range of the curve for a particular trait. Examples of polygenic traits include skin color, eye color, hair color, body shape, height, and weight.

Is hair 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. The result is the perception of continuous gradation in the expression of these traits.

Is human height a polygenic trait?

​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.

Is color blindness a polygenic trait?

In polygenic inheritance, more than one pair of alleles determines the phenotype. Each dominant allele is additive to the overall phenotype. Human skin color is a polygenic trait.

Which of the following is an example of a trait?

Traits are essentially physical characteristics. These include things such as fin length, body shape, color patterns, eyesight, and muscle definition.

What is a polygenic trait biology quizlet?

polygenic triats. a trait that is controlled by several pairs of genes; different combinations of all the genes contribute to the trait in varying degrees. multiple allele traits.

Which of the following is an example of polygenic inheritance AP Bio?

Human skin colour is an example of such polygenic inheritance which is controlled by three pairs of polygenes A, B and C.

What is an example of a trait that is determined by multiple alleles?

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.

Are freckles polygenic?

Traits with polygenic determinism correspond to the classical quantitative characters, as opposed to the qualitative characters with monogenic or oligogenic determinism. In essence instead of two options, such as freckles or no freckles, there are many variations, like the color of skin, hair, or even eyes.

Is skin color a dominant or recessive trait?

The darkest skin is due to six dominant “doses” and the lightest skin is due to six recessive “doses”. Varying combinations of the alleles result in seven discrete colors. Mendel's laws (reviewed in slides) show that there are different combinations of the three expressed genes for each of the seven colors.

Is skin color a multifactorial trait?

Examples of Multifactorial Traits: Fingerprint patterns, height, eye color, and skin color... Eye color: iris colored by the pigment -- melanin. ... Skin color: melanin production by melanocytes in skin.

Can two short parents have a tall child?

It is possible to have a tall child from relatively short parents. Whilst genetics play a major role, other modifiable factors can help increase such a child's height.

What are polygenic traits Mcq?

This set of Biology Multiple Choice Questions & Answers (MCQs) focuses on “Polygenic Inheritance”. ... Traits which are generally controlled by three or more genes are known as polygenic traits.

How Is height a polygenic trait?

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. There is also a wide range of skin color across people. Skin color is also a polygenic trait, as are hair and eye color.

How are polygenic traits different from traits that only require 2 genes?

8) How are polygenic traits different from traits that only require 2 genes? The polygenic traits have a wide variation in each trait. ... The children can have more tall genes than either parent. The environment also plays a role in the expression of traits.
