Pleiotropy is the phenomenon whereby a single gene has multiple consequences in numerous tissues. Pleiotropic effects stem from both normal and mutated genes, but those caused by mutations are often more noticeable and easier to study. Pleiotropy is...

The products of many genes have several different effects or phenotypes in cells, a phenomenon known as pleiotropism or pleiotropy. Levels of pleiotropy vary from one gene to another, giving rise to expressions such as low-pleiotropy or great...

Pleiotropy occurs when a single gene influences multiple phenotypic traits. Consequently, a new mutation in the gene will have an effect on all traits simultaneously. This can become a problem when selection on one trait favours one specific mutant,...
