What is an example of pleiotropy?
Table of Contents
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.
Which is called a pleiotropic gene?
Pleiotropic gene: A gene that affects more than one phenotype. Pleiotropy results in different expressions at the phenotypic level. For example, sickle cell anaemia and cystic fibrosis in man.
What does the word pleiotropy mean?
: producing more than one effect especially : having multiple phenotypic expressions a pleiotropic gene.
What is Priya 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 is Pluto Tropic Jin?
Correct Option: A. Explanation: Pleiotropism is the phenomenon of multiple effects of a gene in which a single pair of genes influences more than one character at the same time.
What is pleiotropic action?
Pleiotropic effects of a drug are actions other than those for which the agent was specifically developed. These effects may be related or unrelated to the primary mechanism of action of the drug, and they are usually unanticipated.
What does pleiotropic mean biology?
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 a pillow trophy?
Which disease is not related to pleiotropy?
So, the correct option is ‘Erythroblastosis foetalis’.
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.
What is a pleiotropic disease?
Pleiotropy refers to disorders where multiple, seemingly unrelated organ systems are affected. For example, one individual in a pedigree may exhibit cardiac arrhythmia, whereas another individual with the same disorder in either the same or different pedigree shows muscle weakness and deafness.
What is the meaning of pleiotropic?
Definition of pleiotropic.: producing more than one effect; especially: having multiple phenotypic expressions a pleiotropic gene.
What is a pleiotropic gene?
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. Mutation in a pleiotropic gene may have an effect on several traits simultaneously,
What is an example of pleiotropic inheritance?
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. What causes tooth decay?
What is universal pleiotropy in biology?
This view of pleiotropy, “universal pleiotropy”, defined as locus mutations being capable of affecting essentially all traits, was first implied by Ronald Fisher ‘s Geometric Model in 1930. This mathematical model illustrates how evolutionary fitness depends on the independence of phenotypic variation from random changes (that is, mutations).
