Definition of pleiotropy in English:

pleiotropy

noun plʌɪˈɒtrəpiplīˈätrəpē

mass nounGenetics

The production by a single gene of two or more apparently unrelated effects.
〔遗传〕基因多效性，多向性
Example sentencesExamples
- These salutary effects of ezetimibe on statin levels presumably enhance the beneficial effects attributed to statin pleiotropy.
- At the level of populations, the scaling of mutational effects with pleiotropy can be addressed via the neutral theory of molecular evolution.
- If gene effects on the trait and fitness are correlated due to pleiotropy, genes of large effect on the trait will remain at much lower frequencies.
- These studies demonstrated that performance and preference of host-plant use may be genetically associated by linkage or pleiotropy, and evolve as correlated traits.
- In this study, three factors affecting the distribution of fixed mutational effects are evaluated: pleiotropy, drift, and stabilizing selection.

Derivatives

pleiotropic

adjective plʌɪəˈtrɒpɪkplʌɪəˈtrəʊpɪk

Genetics

Similarly, mutations within the Drosophila CBP homolog have wide-ranging pleiotropic phenotypes.
Example sentencesExamples
- There appears to be a common logic that can be discerned behind the list of these pleiotropic changes in cell metabolism.
- Conservation of this function in humans may explain many of the pleiotropic phenotypes of cartilage hair hypoplasia.
- Many mutants died or showed pleiotropic defects casting doubt on the specificity of their retinal phenotype and were not included in this report.
- Many semidwarf mutants have pleiotropic effects on traits other than culm length.

pleiotropism

noun

Genetics

Pleiotropism is a hallmark of cytokines and growth factors; yet, the underlying mechanisms are not clearly understood.
Example sentencesExamples
- The gene exhibited pleiotropism by influencing not only oleate and linoleate, but also levels of palmitate, gadoleate, and total saturated fatty acids.
- If the majority of mutations have large negative impacts on fitness, pleiotropism will act to increase their selective effects in nature.

Origin

1930s: from Greek pleiōn 'more' + tropē 'turning'.
