How to use pleiotropic in a sentence. In genetics, Pleiotropy is defined as the expression of multiple traits by a single gene. Pleiotropy is derived from a Greek word meaning more ways. A simple example of a Pleiotropy is phenylketonuria is a disease. It is a genetic disorder caused by the low metabolism of the amino acid phenylalanine in the body cells. Pleiotropy is a phenomenon increasingly recognized by the usage of hypothesis-free exome sequencing rather than candidate gene approaches to identify novel disease genes.
Such genes responsible for multiple effects are called pleiotropic genes. Vestigeal wings in Drosophila are caused by a recessive gene in homozygous condition.

Studies have shown that genes can have varying degrees of pleiotropy and that, on average, deleting genes with higher degrees of pleiotropy has harmful effects on the organism (Guillaume & … Define pleiotropic gene. pleiotropic gene synonyms, pleiotropic gene pronunciation, pleiotropic gene translation, English dictionary definition of pleiotropic gene. also plei·ot·ro·pism n.

By definition, pleiotropy is a situation in which one gene controls for the expression of multiple phenotypic traits. These traits don’t have to be clearly linked, i.e., eye shape and eye color, but can instead be completely unrelated. Pleiotropy is a phenomenon increasingly recognized by the usage of hypothesis-free exome sequencing rather than candidate gene approaches to identify novel disease genes. It refers to the effect that mutations in one and the same gene may lead to multiple, seemingly unrelated diseases. In adopting Williams' concept of pleiotropy, specific pleiotropic genes were suggested by Kirkwood and Holliday (1979) in the disposable-soma theory of aging, namely, genes that control the level of somatic maintenance versus the level of reproductive output (Kirkwood 1985). Direct selection of life span in Drosophila melanogaster Pleiotropy refers to the phenomenon in which a single gene controls several distinct, and seemingly unrelated, phenotypic effects.
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
After overcoming the LD challenge, our results disclosed several genetic variants simultaneously affecting BW and EN with some of them pointing to most promising pleiotropic genes, as we discuss below. The first SNP that served as a proxy to a plausible pleiotropic gene was rs314529054 (GGA6). Main conclusion Transformation from q to Q during wheat domestication functioned outside the boundary of threshability to increase yield, grains m−2, grain weight and roundness, but to reduce grains per spike/spikelet. Mutation of the Q gene, well-known affecting wheat spike structure, represents a key domestication step in the formation of today’s free-threshing, economically important

Pleiotropy is a condition in which a single gene influences more than one phenotypic trait in an organism. Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits, an example being phenylketonuria, which is a human disease that affects multiple systems but is caused by one gene defect. Consequently, a mutation in a pleiotropic gene may have an effect on some or all traits simultaneously.
