La gran implicacion de la epistasis en los programas de mejoramiento genetico de plantas reside en el hecho que, en su presencia, los estimados de los componentes de la varianza genetica aditiva y de dominancia quedan sesgados, lo que resulta en interpretaciones incorrectas en los estimados de parametros geneticos importantes, como el coeficiente de heredabilidad y la respuesta esperada con la seleccion (Eta-Ndu y Openshaw, 1999).
1995) suggested that epistasis plays a significant role in elite maize hybrids production.
En esta variable se presenta un tipo de interaccion de epistasis recesiva o doble recesiva, ya que segun Mather y Jinks (1971) cuando los efectos [h], [i] y [l] tienen los mismos signos, existe este tipo de interaccion epistatica.
Epistasis that has been ignored in most genetic association studies might explain a large portion of genetic variation for complex traits.
An interesting example of epistasis has been discovered in white clover (Trifolium repens).
Biological epistasis results from physical interactions among biomolecules (e.
Topics include genome-wide analysis of epistasis, cross-modal correlation mining using graph algorithms, a decition tree for remotely sensed image data, the business impact of predictive analytics, and semantics enhancing knowledge discovery.
The current limitations and assumptions of this approach, which include lack of joint distributions, limited information on epistasis and the influence of other potential variables, such as exposure, are discussed.
Three hypotheses of nonadditive gene action may explain heterosis: overdominance (Shull 1908, East 1936), dominance (Bruce 1910) and epistasis (Stuber et al.
The assumptions of this formula include: all the genes in control of the trait are unlinked; they affect the trait equally in size and direction; and there is no dominance or epistasis effects involved.
