Pleiotropy and the Preservation of Perfection

Science, 1998
A mathematical model is presented in which a single mutation can affect multiple phenotypic characters, each of which is subject to stabilizing selection. A wide range of mutations is allowed, including ones that produce extremely small phenotypic changes.

On the definition and measurement of pleiotropy

Trends in Genetics, 2013
Pleiotropy, a 103-year-old concept [1], refers to the phenomenon of one mutation affecting multiple traits. Compared with the fundamental importance of pleiotropy in genetics, development, evolution, and medicine, our empirical knowledge of the prevalence and mechanism of pleiotropy is scarce [2].

Seven types of pleiotropy

The International Journal of Developmental Biology, 1998
Pleiotropy, a situation in which a single gene influences multiple phenotypic traits, can arise in a variety of ways. This paper discusses possible underlying mechanisms and proposes a classification of the various phenomena involved.
