a variety of polypeptides which have pleiotropic effects on cell differentiation, The regulation of reporter gene transcription by growth hormone in cultured

Thus, it is not surprising that mutations in genes which function in melanocyte development or melanogenesis frequently cause pleiotropic effects involving sight, hearing and neurologic functioning. Many pleiotropic effects recently studied in mice have come from investigating mutagenesis screens and knockout mutations.

plei·o·trop·ic gene. ( plī'ō-trō'pik jēn) A gene that has multiple, apparently unrelated, phenotypic manifestations. Synonym (s): polyphenic gene. Medical Dictionary for the Health Professions and Nursing © Farlex 2012. A pleiotropic gene is a single gene that regulates more than one trait. The term pleiotropy is originated from the Greek words plelios, that means "many," and tropic, indicates “affecting.” It is defined as those genes that affect multiple, seemingly unrelated, phenotypes and are therefore called pleiotropic genes. Pleiotropy refers to the phenomenon in which a single gene controls several distinct, and seemingly unrelated, phenotypic effects.

Mutations with manifold effects are known from every organism which has been Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits, an example being phenylketonuria, which is a human disease that Mar 1, 2017 Pleiotropy, when considered at the molecular level of genes, is the case in which perturbation of one gene influences multiple phenotypic traits ( Oct 12, 2019 Class: 12th Subject: Biology Chapter: Principles of Inheritance and Variation Topic Name: Pleiotropic Gene (5.36) Points covered in this video:- Oct 19, 2010 Pleiotropy occurs when a single mutation or gene affects multiple distinct phenotypic traits (1). Pleiotropy has broad implications in genetics (1–3), Dec 1, 1995 Questions arise as to how the agouti gene, one of the major coat color genes, is involved in the pleiotropic lethality in early development and pleiotropy.

Introduction • Defination- Pleiotropism is defined as when one gene influences multiple, unrelated phenotypic traits • Pleiotropy describes the genetic effect of a single gene on multiple phenotypic traits • Mutation in a pleiotropic gene may have an effect on some or all traits • Mechanism of pleiotropy in most (b) Divergence in regulation of genes within a shared pathway: (left) constraints of pleiotropy can be mitigated if the pleiotropic gene is regulated differently by the same environmental cue at different life stages or in different traits; (right) it can also be mitigated if the pleiotropic gene regulates the same downstream partner differently at different life stages or in different traits. Pleiotropic gene action can limit the rate of multivariate evolution when natural selection, sexual selection or artificial selection on one trait favours one specific version of the gene, while selection on the other traits favours a different allele. In the history of this discussion, many have argued that ‘true’ pleiotropy exists only if the pleiotropic element is contained within a single gene ( Figure 1) [ 7]. For example, a knock-in of an R120G mutation in Cryab in mice causes cataracts and cardiomyopathy [ 8 ].
