What do you mean by pleiotropic gene?
A pleiotropic gene is a single gene that controls more than one trait. © 2008 Nature Education All rights reserved. During his study of inheritance in pea plants, Gregor Mendel made several interesting observations regarding the color of various plant components.
What is an example of a pleiotropic gene?
A mutation in a gene can result in pleiotropy. One example of pleiotropy is Marfan syndrome, a human genetic disorder affecting the connective tissues. This disease commonly affects the eyes, heart, blood vessels, and skeleton. Marfan Syndrome is caused by a mutation in a human gene resulting in pleiotropy.
What is pleiotropy gene Class 12?
In genetics, Pleiotropy is defined as the expression of multiple traits by a single gene. Pleiotropy is derived from a Greek word meaning more ways. A simple example of a Pleiotropy is phenylketonuria is a disease. It is a genetic disorder caused by the low metabolism of the amino acid phenylalanine in the body cells.
What are pleiotropic genes and Polygenes?
The ability of a gene to influence more than one trait is called pleiotropy whereas in polygenic inheritance the inheritance is influenced by a number of independent genes, each having a small and similar effect.
What is Pluto Tropic Jin?
Pleiotropy is the expression of multiple traits by a single gene. Gene pleiotropy is focused on the number of traits and biochemical factors impacted by a gene. Developmental pleiotropy is focused on mutations and their influence on multiple traits.
How are pleiotropic genes inherited?
Alleles of pleiotropic genes are transmitted in the same way as alleles of genes that affect single traits. In these cases, the difference is that the phenotype contains multiple elements. These elements are specified as a package, and there would be both a dominant and recessive version of this package of traits.
Introduction • Defination- Pleiotropism is defined as when one gene influences multiple, unrelated phenotypic traits • Pleiotropy describes the genetic effect of a single gene on multiple phenotypic traits • Mutation in a pleiotropic gene may have an effect on some or all traits • Mechanism of pleiotropy in most cases …
What is the difference between pleiotropy and epistasis?
Epistasis: When a gene at one location (locus) alters the phenotypic expression of a gene at another locus. Pleiotropy: A single gene controlling or influencing multiple phenotypic traits.
What is a pillow trophy?
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.
What do you mean by pillow trophy?
Pleiotropy refers to the expression of multiple traits by a single gene. These expressed traits may or may not be related. Pleitropy was first noticed by geneticist Gregor Mendel, who is known for his famous studies with pea plants.
Who created gene mapping?
Alfred H. Sturtevant
One hundred years ago, in 1913, Alfred H. Sturtevant helped lay the foundations of modern biology by mapping the relative location of a series of genes on a chromosome.
Are most genes technically pleiotropic?
That is, a few genes have extensive pleiotropic effects, but most genes are more limited in their effects on the phenotype. However, nearly all genes have some degree of pleiotropy.
What are some examples of pleiotropy?
Abnormal tall height.
What is pleiotropy in genetics?
Pleiotropy is a condition in which a single gene influences more than one phenotypic trait in an organism.
What are pleiotropic effects?
Medical Definition of Pleiotropic. Pleiotropic: Producing or having multiple effects from a single gene. For example, the Marfan gene is pleiotropic, potentially causing such diverse effects as long fingers and toes (arachnodactyly), dislocation of the lens of the eye, and dissecting aneurysm of the aorta.
