genetic dominance 中文意思是什麼
genetic dominance
解釋
遺傳優勢-
This paper presents a single - locus tetra - allelic binary genetic algorithm based on the concept of dominant and recessive genes, which is named full dominance - recessive diploid ga. this ga features separating dominant one - zero with recessive one - zero
基於生物進化遺傳理論中有顯性、隱性遺傳因子的理念，本文提出了一種採用單點四進制編碼的遺傳演算法，即完全顯隱性二倍體遺傳演算法。 -
Genetic models were constructed for qtl mapping by two - dimensional searching. corresponding analysis methods were also proposed, which could estimate additive effects, dominance effects, epistatic effects of additive by additive, additive by dominance, dominance by additive, dominance by dominance, and could predict their interaction effects with environments
構建了可以估汁加性效應、顯性效應、加加、加顯、顯加、顯顯上位性效應以及預測這些效應與環境互作效應的qtl定位兩維搜索遺傳模型，提出了相應的分析方法。 -
The estimation of additive and dominance effects through qtl analysis by one - dimensional search while ignoring epistases showed similar accuracy to that by two - dimensional search by including epistases. existence of epistases could decrease the precision for the estimation of additive and dominance effects. the estimation of genetic main effects would be biased if ignoring the interaction effects of qtl x environment ( qe )
忽略上位性效應的一維搜索qtl分析對加性效應和顯性效應的估計精度與包括上位性的兩維搜索qtl分析對這兩種效應的估計精度相差不大，上位性的存在可能會降低對這兩種效應估計的精度；忽略qtl環境（ qe ）互作效應會導致對遺傳主效應的有偏估計，而包括qe互作效應的多環境聯合分析能夠提高對遺傳主效應的估計精度。 -
Monte carlo simulations were conducted to study the new approaches of qtl mapping, the results indicated that general least squares ( gls ) method, which was widely applied in mixed linear model, could unbiasedly estimate all genetic main effects, including additive effects, dominance effects and epistatic effects of additive by additive, additive by dominance, dominance by additive, dominance by dominance. the interaction effects between genetic main effects and environments could also be predicted unbiasedly by linear unbiased prediction ( lup ). the heterosis prediction based on qtl effects was also unbiased
對新提出的qtl分析方法進行了montecarlo模擬研究，結果表明，廣泛應用於混合線性模型的廣義最小二乘法（ gls ）能夠無偏估計加性效應，顯性效應以及加加、加顯、顯加、顯顯上位性效應等各項遺傳主效應；運用線性無偏預測法（ lup ）能夠無偏預測上述各項遺傳主效應與環境的互作效應；基於qtl效應的雜種優勢預測也是無偏的。 -
In this article, we review isolation methods, developmental status and genetic characteristics of microsatellites, and their applications in studies on population study, pedigree analysis, assessment of genetic diversity, and construction of genetic maps in the marine mollusks, and analyzed the causes resulting to null allele, stutter bands, short allele dominance and allelic dropout, and their effects on genotyping of microsatellite
本文對海洋貝類微衛星分離方法、開發現狀、遺傳學特性以及在種群遺傳、家系分析、遺傳多樣性評價等方面的最新研究進展進行了綜述，並分析了微衛星分析中無效等位基因、 「結巴」帶、短等位基因顯性和等位基因「擴增丟失」現象的產生原因以及對微衛星基因型判讀帶來的影響。 -
Numerical experiments with four test functions are performed, and some valuable conclusions are reached. first, the efficacy of full dominance - recessive diploid genetic algorithm outperforms the standard genetic algorithm ( sga ) in high - dimensional functions. the time complexity of the proposed ga approximates a polynomial multiple of that of sga
通過對四個常用測試函數用完全顯隱性二倍體遺傳演算法和標準遺傳演算法進行初始解相同的對比試驗，表明完全顯隱性二倍體遺傳演算法在十維以上的高維函數優化問題中解的效果明顯優于標準遺傳演算法，對低維函數優化問題也不劣於標準遺傳演算法。
