What is an example of polygenic inheritance?

What is an example 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.

What is polygenic traits in biology?

A polygenic trait is a characteristic, such as height or skin color, that is influenced by two or more genes. Because multiple genes are involved, polygenic traits do not follow the patterns of Mendelian inheritance. Many polygenic traits are also influenced by the environment and are called multifactorial.

What is polygenic gene interaction?

Biology definition: Polygenic inheritance is a non-Mendelian pattern of inheritance in which a particular trait is produced by the interaction of genes at many loci (i.e. polygenes). Etymology: “poly”, meaning “many”.

What are 3 examples of polygenic traits?

Examples of polygenic traits include skin color, eye color, hair color, body shape, height, and weight.

What are polygenes Class 12?

Solution : When a Character is controlled by two or more than two pairs of genes,the genes are called polygenes.

What is Oligogenic traits?

Oligogenic traits are characteristics with a distribution that is discrete and the expression of which is governed by a few genes with large effects. These traits are very important in the breeding programs of various crops (AGRAMA et al., 2007; BRESEGHELLO; SORRELLS, 2006).

What is the simple definition of epistasis?

Definition. noun, plural: epistases. (genetics) The interaction between nonallelic genes at two or more loci resulting in one gene masking the phenotypic expression of another gene. (medicine) The arrest of a secretion or bodily discharge.

What is Polygene explain how it is originated?

A polygene refers to a group of genes that when expressed together produce a particular phenotype or trait. The trait produced is therefore a result of the expression of multiple genes. This type of trait is referred to as a polygenic trait. In humans, it is exemplified by skin colour, height, and weight.

How do polygenes control traits?

Polygenic trait refers to a trait that is controlled by multiple non-allelic genes. These genes are called polygenes. They are a group of genes that, when turned on, are expressed as a unit. Each of them produces an effect that adds up to the trait.
