It designates the occurrence of a single gene affecting multiple traits, and is a hugely important concept in evolutionary biology. Evolutionary adaptation is often likened to climbing a hill or peak. 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.

Huvudskillnaden mellan epistasis och pleiotropi är att epistasis är fenomenet där en gen på ett ställe förändrar det fenotypiska uttrycket av. epistasis. Denna interaktion av nonalleliska gener - epistas- det observeras i fallet pleiotropy.

Epistasis, pleiotropy, dihybrider och mutationer håller jag på att läsa mer om just nu. För att vara mindre precis så sammanfattar jag alla tidigare föreläsningar för att vara förberedd till tentan som kommer till slutet av oktober. We conclude that epistasis, by differentially affecting both the canalization and mean values of the traits of a pleiotropic domain, causes variation in the covariance structure.

Epistasis - The effects of one gene are altered by the effects of a different gene. Pleiotropy - Two or more aspects of phenotype are affected by one gene. In my head, these two are exactly the same. Can someone help me understand to draw a clear difference between the two? Dominant epistasis. In some cases, a dominant allele at one locus may mask the phenotype of a second locus. This is called dominant epistasis, which produces a segregation ratio such as 12:3:1, which can be viewed as a modification of the 9:3:3:1 ratio in which the A_B_ class is combined with one of the other genotypic classes that contains a dominant allele.
