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 c in QTc stands for corrected. The QTc is the QT interval with a formulated correction based on the patient's heart rate (HR). The faster the HR the shorter the QT interval.The QTc may not always be accurate, but is commonly used for diagnostic purposes. Bazett's formula is used to determine QTc (well according to wikipedia it is).hat this means is that another beat, from another part of the heart, may occur. Long QT Syndrome (LQTS) is a condition purely diagnosed by an electrocardiogram (ECG). This condition is represented by a long QT interval, hints the name. This represents delayed ventricular repolarization.
