Can a gene influence multiple traits?

Can a gene influence multiple traits?

Pleiotropy (from Greek πλείων pleion, “more”, and τρόπος tropos, “way”) occurs when one gene influences two or more seemingly unrelated phenotypic traits. Such a gene that exhibits multiple phenotypic expression is called a pleiotropic gene.

Can one gene control more than one trait list an example?

Explanation: A trait that is controlled by more than one gene is called polygenic which translates to “multiple genes”. The genes work together to make one trait. Examples are skin, eye and hair color.

How can a single gene influence many traits?

When one single gene starts affecting multiple traits of living organisms, this phenomenon is known as pleiotropy. A mutation in a gene can result in pleiotropy. One example of pleiotropy is Marfan syndrome, a human genetic disorder affecting the connective tissues.

Is it possible for a trait to be controlled by more than one gene?

Polygenic Traits Many human traits are controlled by more than one gene. These traits are called polygenic traits. The alleles of each gene have a minor additive effect on the phenotype. There are many possible combinations of alleles, especially if each gene has multiple alleles.

How many genes affect traits?

Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.

When a single gene locus affects more than one trait what is it called?

Pleiotropy. When a single gene affects the expression of more than one phenotypic trait, the phenomenon is known as pleiotropy (from the Greek pleio meaning “more” and “trop, meaning “change”).

When more than one gene interacts with each other to influence the outcome of a single character it is known as?

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.

Are all traits represented by only one gene?

While a few traits are due to only one gene (and its alleles), most human genetic traits are the product of interactions between several genes. The traits listed on the next pages have commonly been presented as being determined by single genes.

How do genes influence traits?

Genes (say: jeenz) play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: curly or straight hair, long or short legs, even how you might smile or laugh.
