epistasis词源英文解释
epi- + -stasis, after earlier epistatic, by analogy with metastatic : metastatis and like pairs Note: The term epistatic was introduced, along with hypostatic, by the English biologist William Bateson (1861-1926) in "Facts Limiting the Theory of Heredity" ("Address delivered at the International Zoological Congress, before the Section of Cytology and Heredity, August 23, 1907"), Science, series 2, vol. 26 (July-December, 1907), issue of November 15, 1907, p. 653: "Till lately we spoke of the relations between the gray color of the mouse to the black color in terms of dominance …We can perhaps best express the relation between the gray and the black by the use of metaphor 'higher and lower,' and I therefore suggest the term epistatic as applicable to characters which have to be, as it were, lifted off in order to permit the lower or hypostatic character to appear."
The first known use of epistasis was circa 1917

epistasis 例句
1 This phenomenon is known as epistasis.
2 In epistasis, the interaction between genes is antagonistic, such that one gene masks or interferes with the expression of another.
3 We also derive this power-law relation theoretically by incorporating clonal interference and diminishing-returns epistasis into a dynamical model of changes in mean fitness over time.
4 We also present evidence that the targets of natural selection change over time, as epistasis and historical contingency alter the strength of selection on different genes.
5 These were controlled by multiple allels or by loci with allels that segregate independently whereby epistasis also may have played a role.
这些是受复等位基因或含分离等位基因的位点支配的，上位性也可能靠它而起了作用。
6 And indeed, bioengineering is where epistasis might cause us the most trouble.
7 The reason for outbreeding depression is most likely going to be some sort of antagonistic epistasis, deleterious gene-gene interactions.
8 The goodness of fit test of genetic model was significant, indicated that besides additive-dominance, other factors, such as epistasis, might affect grain plumpness.
一些组合的遗传模型的离回归测验显著，表明除了基因的加性-显性作用外，还有一些因子对充实度有影响。

11 Often the biochemical basis of epistasis is a gene pathway in which expression of one gene is dependent on the function of a gene that precedes or follows it in the pathway.
12 Dantas views the concept of 'genetic epistasis', in which two or more genes influence one another, as strength in numbers.
13 The existence of extensive ALS genome databases will enable the first comprehensive studies of epistasis, characterizing the interactions of numerous genes to perturb the viability of motor neurons.
14 Often the biochemical basis of epistasis is a gene pathway in which the expression of one gene is dependent on the function of a gene that precedes or follows it in the pathway.
