n. 【遺】上位(遺傳要素的)抑他性。 “complicated epistasis“ 中文翻譯：   復雜上位顯性“dominant epistasis“ 中文翻譯：   顯性上位酌“epistasis effect“ 中文翻譯：   上位效應“epistasy epistasis“ 中文翻譯：   上位“over-epistasis“ 中文翻譯：   超上位作用“recessive epistasis“ 中文翻譯：   隱性上位酌“duplicate dominant epistasis“ 中文翻譯：   重復顯性上位“duplicate recessive epistasis“ 中文翻譯：   重復隱性上位“epistasio“ 中文翻譯：   佩德羅-阿韋利努“epistasy“ 中文翻譯：   上位“epistais“ 中文翻譯：   曲差“epist“ 中文翻譯：   Epis(t) ＝Epistle(s). “epistates“ 中文翻譯：   首席執法官“epispore“ 中文翻譯：   孢子外壁“epistatic“ 中文翻譯：   上位的“episplenitis“ 中文翻譯：   脾被膜炎

epistaxis

Because traditional epistasis measure methods can only reflect the extent of interaction between all genes in the chromosome , we used correlation length analysis and epistasis measures on the fitness landscapes of schemata to test the extent of interdependence between some certain gene loci in study 針對傳統的測試基因關聯的方法只能給出染色體中所有基因位的整體關聯程度的情況，通過在模式適應值曲面上分別進行相關長度測試和基因關聯測試，以研究染色體中一些特定位之間的基因關聯程度。

Meanwhile , for the statistical analysis model of epistasis introduced by davidor , we discussed epistasis variance and epistasis correlation , and further induced two theorems , of which we gave strict mathematic proof 同時對基因關聯進行了統計分析，討論了基因關聯方差及基因關聯相關系數，歸納出兩個定理并給予了嚴格的數學證明。

Epistasis and genotype x environment interaction exist universally and have been testified by a lot of researches . these effects play an important role in inheritance , evolution and heterosis in plants 上位性和基因型環境互作存在的普遍性利它們在植物遺傳、進化和雜樸優勢中的重要作用已為大量研究所證實。

Then , we investigated the epistasis of gas using walsh - schema transform , and further evaluated the epistasis order for the < wp = 5 > continuous function optimization problems 利用walsh模式變換對遺傳算法基因關聯問題進行了分析，并對連續函數優化問題的基因關聯階數進行了估計。

4 . we probed into some methods to measure ga - hardness . first of all , we compared three approaches : fdc , correlation length , and epistasis measures 4 .對常見的幾種遺傳算法困難度測試方法（ fdc測試、相關長度測試與基因關聯測試法）進行了分析比較。

Additionally , several test problems with epistasis for gas were described 闡述了幾個常見的基因關聯問題。

These were controlled by multiple allels or by loci with allels that segregate independently whereby epistasis also may have played a role . 這些是受復等位基因或含分離等位基因的位點支配的，上位性也可能靠它而起了作用。
