Popis:	Several methods have been proposed over the years to detect linkage between a marker gene and quantitative trait locus (QTL). Use of isozymes and restriction fragment length polymorphisms as genetic markers, has encouraged the development of new methods to detect linkage. We present three methods to detect linkage and two methods to measure recombination frequency (r). The three methods that detect linkage can be used when a single QTL or a tightly linked cluster of QTLs control the quantitative trait. The two methods that measure recombination frequency could not be used in the latter case because r would not be properly estimated. Procedures to calculate the additive and dominance gene effects of the QTL and the respective variances of these estimates were also presented.
