Which statement best describes the potential confusion in early studies of inheritance patterns for skin color?

Answer. The statement about “potential confusion in studies of inheritance patterns for skin color” is that “The polygenic trait appeared as incomplete dominance.” Explanation: Incomplete dominance results when a new offspring is produced which doesn’t have the characteristic features of both the parents.

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.

What represents polygenic inheritance of traits?

Answer. Polygenic inheritance is a pattern of inheritance when the trait is not controlled by one gene, but by multiple genes that each make a small contribution to the overall outcome. In this case, the trait of the eye color is controlled by different genes (for blue, green, and brown eye colors).

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.

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.

In humans, the inheritance pattern followed by blue eyes is considered similar to that of a recessive trait (in general, eye color inheritance is considered a polygenic trait, meaning that it is controlled by the interactions of several genes, not just one).

6 replies. “Definitely not monogenic, as there are multiple types of colorblindness (monochromatic, red-green, blue-yellow, etc.) that would be hard to explain with a single pair of genes.

Examples of polygenic traits include skin color, eye color, hair color, body shape, height, and weight. This trait is reportedly due to a single gene; the presence of freckles is dominant, the absence of freckles is recessive1.

Is color blindness Mendelian?

Colour blindness is a usually a genetic (hereditary) condition (you are born with it). Red/green and blue colour blindness is usually passed down from your parents. The gene which is responsible for the condition is carried on the X chromosome and this is the reason why many more men are affected than women.

Color blindness isn’t common in females because there’s a low likelihood that a female will inherit both genes required for the condition. However, since only one gene is needed for red-green color blindness in males, it’s much more common.
