Which of the following is a polygenic trait?

Which of the following is a polygenic trait?

In humans, height, skin color, hair color, and eye color are examples of polygenic traits. The term polygenic comes from poly, meaning “many” and genic, meaning “of genes”.

What is gene inheritance in terms of polygenic traits?

Polygenic inheritance refers to the kind of inheritance in which the trait is produced from the cumulative effects of many genes in contrast to monogenic inheritance in which the trait results from the expression of one gene (or one gene pair).

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.

What is a polygenic trait example?

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 are examples of polygenic inheritance?

Some examples of polygenic inheritance are: human skin and eye color; height, weight and inteligence in people; and kernel color of wheat.

Who is observed by multiple gene inheritance?

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.

How is the expression of polygenic traits determined quizlet?

The expression of polygenic traits: is determined by genes at several loci in conjunction with environmental factors.

How can a polygenic trait be easily identified quizlet?

are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Human height, eye and hair color are examples of polygenic traits.

What is polygenic inheritance explain with example?

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 is 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 is eye color an example of polygenic inheritance?

The presence of one dominant allele produces the green color, while having no dominant alleles results in blue eye color. Like eye color, skin color is an example of polygenic inheritance. This trait is determined by at least three genes and other genes are also thought to influence skin color.

Are human traits polygenic or Mendelian?

Surprisingly, most traits in humans, and in fact most traits in most organisms, are polygenic. Mendelian traits, although we spend a lot of time talking about them, are really the exception.

What is polygenic inheritance in plants?

Polygenic inheritance in plants includes the colour and shape of the stem, pollen, flower, yield, oil content, size of a seed, time to mature or flower, etc. Brief description of some of the traits: Kernel colour of the wheat: The three independent pairs of alleles are involved in the expression of kernel colour of wheat.
