one-dimensional search meaning in English

一维搜索

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 )
忽略上位性效应的一维搜索qtl分析对加性效应和显性效应的估计精度与包括上位性的两维搜索qtl分析对这两种效应的估计精度相差不大，上位性的存在可能会降低对这两种效应估计的精度；忽略qtl环境( qe )互作效应会导致对遗传主效应的有偏估计，而包括qe互作效应的多环境联合分析能够提高对遗传主效应的估计精度。
