A condition in which a single mutant gene affects more than one distinct characteristic of an individual is referred to as Pleiotropy.
<h3>What is Pleiotropy?</h3>
- Pleiotropy occurs when one gene influences two or more seemingly unrelated phenotypic traits.
- Such a gene that exhibits multiple phenotypic expressions is called a Pleiotropic gene.
- Pleiotropy can arise from several distinct but potentially overlapping mechanisms, such as gene pleiotropy, developmental pleiotropy, and selectional pleiotropy.
- An example of pleiotropy is phenylketonuria.
- So, when a single trait mutant gene controls more than one trait it is called Pleiotropy and it can cause the various syndrome.
