Interval mapping of quantitative trait loci employing correlated trait complexes
Article Abstract:
The heritability related to a quantitative trait locus (QTL) linearly depends on the quantity of the traits, and for some traits x and y, H(super 2)(sub xy)(A/a) is > or = H(super 2)(sub x)(A/a). The inequality is also valid if y is not a function of A/a. For the nongenetic factors and isolation of genes from other chromosomes, the x and y are interrelated within the groups AA, Aa and aa. An increased analysis capability of the QTL mapping model is possible by considering the correlations of the quantitative traits.

Correcting the bias of Wright's estimates of the number of genes affecting a quantitative character: a further improved method
Article Abstract:
Wright's method of approximating the number of genes governing quantitative traits takes into consideration the means and variances of the measured characteristics in two parental strains and their offsprings. However, this method does not account for unequal allelic contribution as well as linkage. A modification in the method taking these two parameters into consideration was designed in order to correct the bias of Wright's method.
