What are the characteristics of polygenic traits?

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.

What are 3 examples of polygenic traits?

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

What is polygenic traits give 2 examples?

Instead of being measured discretely, they are often represented as a range of continuous variation. Some examples of polygenic traits are height, skin color, eye color, and hair color.

What is polygenic character?

Many characters that display continuous variation are controlled by genes at many loci. Characters influenced by a group of genes are called polygenic characters. The number of genes involved in the control of some trait is commonly around 10, but may be as large as 100 or so in some cases.

Why do polygenic characteristics traits have many phenotypes?

Why do polygenic characteristics have many phenotypes? Many genotypes are possible with multiple genes. ... If each genotype corresponds to a unique phenotype, then the number of phenotypes is the same: 27 for three genes and 81 for four genes.

What are Polygenes give examples?

Related term: polygene. What are polygenic inheritance examples? Human phenotypes or human physical traits such as hair color, height, skin color, blood pressure, intelligence, autism, and longevity are some of the examples of polygenic inheritance.

What kind of traits are controlled by Polygenes?

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.

What are Polygenes Class 12?

Polygenic inheritance occurs when one characteristic of an organism is controlled by two or more genes. ... It is also termed as more than two contrasting alleles for a gene. The ABO blood group is an ideal example of multiple alleles; in this more than two alleles are present to govern the same character in an organism.

What is a polygenic trait 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.

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.

What are polygenic monogenic traits?

A monogenic trait is a characteristic that is produced by a single gene or a single allele. ... A polygenic trait is a characteristic controlled by two or more genes that are located at different areas on different chromosomes.

What are multifactorial traits?

What is multifactorial inheritance? Multifactorial inheritance is when more than one factor causes a trait or health problem, such as a birth defect or chronic illness. The main factor is genes. But the cause includes other factors that aren't genes, such as: Nutrition.

What do polygenic traits result from?

Polygenic traits are due to the actions of more than one gene and often, their interaction with the environment. These usually result in a measurable range in phenotype, such as height, eye color or skin color. These are known as multifactoral or quantitative characteristics.

How can a polygenic trait be easily identified?

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.

What is the difference between a polygenic trait a pleiotropic trait and a Mendelian trait?

In pleiotropy, a single gene controls a particular character, obeying Mendelian inheritance patterns. In polygenic inheritance, a single trait is controlled by many genes.

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.
