A very broad biological term describing the effect of a gene or alteration of a gene on a phenotype. Usage is created by the context, which can be complex. Some genes have a multiple range of effects across a range of traits and characteristics of organisms. If the subject gene alters, it will have a multiple range of effects on the organism, hence the descriptor operates as defining a type of condition. |
Examples of Pleiotropy:

Arachnodactyly: Causes long fingers and other physical effects. https://en.wikipedia.org/wiki/Pleiotropy https://www.biochem.northwestern.edu/holmgren/Glossary/Definitions/Def-P/pleiotropy.html |
