The Volcano Plots tab contains the following elements:
The volcano plot(s) show the
LOD score for each
trait plotted on the
y-axis versus either the
Estimate of the Additive Effect on the
x-axis or the
Estimate of the Dominance Effect (coded in reference to the effect of the parental line 2 or P2
allele). Each point on the plot represents a
QTL testing location, with points colored by the
chromosome or
linkage group. Negative estimates indicate that there was a decrease in the quantitative trait associated with the allele from parental line 2. The black horizontal line represents a LOD threshold that was either specified on the process
dialog or determined using permutation testing. Points to the upper left or upper right indicate locations with increasing evidence of a significant QTL that have large negative or positive effect on the trait of interest.
