Pleiotropy Summary
663 words, approx. 2 pages 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...

Pleiotropy Summary
479 words, approx. 2 pages 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 Information
564 words, approx. 2 pages
 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,...

Toward a Molecular Understanding of Pleiotropy
08/01/2006: 4,350 words, approx. 15 pages ABSTRACT Pleiotropy refers to the observation of a single gene influencing multiple phenotypic traits. Although pleiotropy is a common phenomenon with broad implications, its molecular basis is unclear. Using functional genomic data of the yeast Saccharomyces cerevisiae, here we show that, compared with...

The Role of Pleiotropy in the Maintenance of Sex in Yeast
03/01/2007: 6,939 words, approx. 23 pages ABSTRACT In facultatively sexual species, lineages that reproduce asexually for a period of time can accumulate mutations that reduce their ability to undergo sexual reproduction when sex is favorable. We propagated Saccharomyces cerevisiae asexually for ~800 generations, after which we measured the change...
