False. polygenic inheritance is the effect of multiple genes on one phenotype and pleiotropy is the effect of one gene on many phenotypes.
Polygenic inheritance is a type of quantitative inheritance in which various independent genes have a similar or additive impact on a single quantitative trait. Multiple gene inheritance or multiple factor inheritance are other terms for polygenic inheritance.
A polygene is a non-epistatic gene that interacts synergistically to affect a phenotypic trait, making a significant contribution to multiple-gene polygenic inheritance.
Pleiotropy takes place when one gene effects two or more phenotypic traits that appear to be unconnected. Pleiotropy occurs when a single gene influences two or more traits. Pleiotropy in the perspective of life history evolution means that a single gene influences the fitness of an organism at two or more ages. Pleiotropy refers to a single gene's genetic effect on various phenotypic traits. Genes that code for a product that is either used by multiple cells or has a cascade-like signal transduction function that affects multiple targets are the underlying mechanism.
Pleiotropy is defined in several ways, including gene pleiotropy, developmental pleiotropy, selectional pleiotropy, and antagonistic pleiotropy.
