Hypostatic: The phenotype altered or suppressed during epistasis; the gene that is not expressed. Modifier genes: Genes that modify the effects of other genes during epistasis. Pleiotropy: A single gene controlling or influencing multiple phenotypic traits. Summary Traits controlled by more than two alleles have multiple alleles.

Pleiotropy vs gene epistasis as a source of life history and functional trade-offs Classic life history trade-offs. Life history theories are typically expressed as gene pleiotropy, such as genes

of epistasis and pleiotropy are not coupled in natural systems, and decoupling them. in the NK model could therefore increase the realism of the model. If the level of.

Genes can either mask each other so that one is considered “dominant” or they can combine to produce a new trait. It is the conditional relationship between two genes that can determine a single phenotype of some traits. Epistasis due to recessive genes is called recessive epistasis. In mice albinism (white coat) is produced by a recessive gene aa. There is a different gene B which in the dominant state (BB and Bb) produces grey coat colour called agouti, and when recessive (bb) leads to black coat colour.

For example, the gene in pea plants that expresses the round or wrinkled texture of seeds also influences the phenotypic expressions of starch metabolism and water absorption. While this process is simple for fitness landscapes where mutations are independent, the interaction between mutations (epistasis) as well as mutations at loci that affect more than one trait (pleiotropy) are crucial in complex and realistic fitness landscapes. Epistasis occurs when one gene affects the phenotypic expression of a second gene: One gene turns on/off production of a pigment while another pigment controls the amount or color of the pigment. Pleiotropy occurs when one gene has more than 1 phenotypic expression. Epistasis either mask or enhances another gene whereas pleiotropy is where a single gene can have many symptoms or a gene that controls several functions or has more than one effect.
