A quantitative trait locus (QTL) is a section of DNA (the locus) that correlates with variation in a phenotype (the quantitative trait).The QTL typically is linked to, or contains, the genes that control that phenotype.he simplest method for QTL mapping is analysis of variance (ANOVA, sometimes called marker regression) at the marker loci. In this method, in a backcross, one may calculate a t-statistic to compare the averages of the two marker genotype groups.
The non-random two-liquid model[1] (short NRTL equation) is an activity coefficient model that correlates the activity coefficients Î³ i {\displaystyle \gamma _{i}} of a compound i with its mole fractions x i {\displaystyle x_{i}} in the liquid phase concerned.
