What is pleiotropic molecule?
Pleiotropy refers to the observation of a single gene influencing multiple phenotypic traits. Although pleiotropy is a common phenomenon with broad implications, its molecular basis is unclear.
What is the meaning of pleiotropic?
Definition of pleiotropic : producing more than one effect especially : having multiple phenotypic expressions a pleiotropic gene.
Which of the following is an example of pleiotropic?
Sickle cell anaemia :- sickle cell anaemia is an example of pleiotropic gene because here the mutation in the single gene carries out a number of changes throughout the body and affects the body in different ways.
What occurs pleiotropy?
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 pleiotropic gene Class 12?
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 is the difference between polygenic and pleiotropic?
Some people confuse pleiotropy and polygenic inheritance. The major difference between the two is that pleiotropy is when one gene affects multiple characteristics (e.g. Marfan syndrome) and polygenic inheritance is when one trait is controlled by multiple genes (e.g. skin pigmentation).
What is pleiotropy and epistasis?
Pleiotropy refers to the phenomenon by which a gene pair at a single locus affects many (more than one) phenotype characteristics. Epistasis is a process by which multiple different gene pairs at different loci interact together to ultimately affect a single trait.
Which is called pleiotropic gene?
Which of the following is a pleiotropic trait?
Deafness and pigmentation in cats, the existence of frizzle traits in cats, Marfan syndrome in humans, sickle cell diseases, Phenylketonuria or PKU, albinism, Austin, and schizophrenia are some of the many examples of pleiotropic. Try to answer the quiz below to check what you have learned so far about pleiotropy.
How is pleiotropy different from polygenic inheritance?
Pleiotropy refers to the single gene having multiple phenotypic expressions, whereas polygenic inheritance refers to a trait being controlled by multiple genes.
When do pleiotropy happens?
Pleiotropy occurs when a single mutation or gene/allele affects more than one phenotypic characteristic.
