What Is Pleiotropy? Definition and Examples - ThoughtCo
网页2019年7月11日 · 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.
Pleiotropy: One Gene Can Affect Multiple Traits - Nature
网页Quite simply, pleiotropy reflects the fact that most proteins have multiple roles in distinct cell types; thus, any genetic change that alters gene expression or function can potentially have...
Pleiotropy - Definition and Examples - Biology Online Dictionary
网页2022年6月16日 · Pleiotropy (biology definition): the condition of having multiple effects. In genetics, it refers to a single gene controlling or influencing multiple (and possibly unrelated) phenotypic traits.
Pleiotropy - Wikipedia
网页Pleiotropy (from Greek πλείωνpleion, 'more', and τρόποςtropos, '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.
Pleiotropy: Definition, Examples And Simple Explanation - Science …
网页2024年6月2日 · By definition, pleiotropy is a situation in which one gene controls for the expression of multiple phenotypic traits. These traits don't have to be clearly linked, i.e., eye shape and eye color, but can instead be completely unrelated.
2.3: Pleiotropy and lethal alleles - Biology LibreTexts
网页Pleiotropy: where one gene affects multiple characteristics. Lethal alleles: alleles that prevent survival when homozygous or heterozygous.
Pleiotropy, epistasis and the genetic architecture of quantitative ...
网页2024年4月2日 · Pleiotropy (whereby one genetic polymorphism affects multiple traits) and epistasis (whereby non-linear interactions between genetic polymorphisms affect the same trait) are fundamental aspects...
12.6.3: Pleiotropy - Biology LibreTexts
网页2021年12月16日 · Rather than abstract “heritable factors,” genes are stretches of DNA found on chromosomes, and most of them encode (specify the sequence of) proteins that do a certain job in the cell or body. In this article, we’ll look in more detail at genes affecting multiple characteristics (pleiotropy).
The pleiotropic structure of the genotype–phenotype map: the ...
网页2011年2月18日 · Pleiotropy refers to the phenomenon of one gene or one mutation affecting multiple phenotypic traits. It has widespread implications in genetics, disease, development,...
Toward a Molecular Understanding of Pleiotropy | Genetics
网页2006年8月1日 · 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.
