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.
How to Care for an Axolotl. This article will tell you how to care for an axolotl. An axolotl is an aquatic salamander related to tiger salamanders; in a tank environment, they will never transform into the adult form, but will remain larvae. They are easy to care for and make enjoyable pets. Keep an eye on the axolotl and make sure to feed it as much as it wants. 2  Any sharp edges in your tank can cause harm to the soft skin and external gills of an axolotl. 3  Light that is too bright frightens axolotls; yet, if it is too dark, the axolotl will grow lazy and fail to thrive.
