Next Trait. Click this button to reach each trait and you can set following parameters.<br />

<strong>QTL</strong> numbers. Set the number of <strong>QTL</strong>s to appear in the file.<br />

Heritability. Requires a value in the range 0.0 to 1.0. Default is 0.8.<br />

Vd/Va. Dominant variance/Additive variance<br />

Vi/Va. Epistatic variance/Additive variance<br />

For the Additive, Dominant, and Epistatic effects you want to see in the simulation, you can select<br />

the following:<br />

Effects direction<br />

Same—All values are positive<br />

Both—Values are positive and negative<br />

Sign's Ratio—Ratio of negative:positive.<br />

Effects distribution<br />

Equal—All effects have the same value<br />

Normal—Values derive from normal distribution<br />

Gamma—Values derive from gamma distribution<br />

Parameter—Value for gamma distribution<br />

Note For more information on effects distribution and the additive, dominant, and epistatic effects,<br />

please refer to the <strong>QTL</strong> <strong>Cartographer</strong>'s manual.<br />

After inputting the parameters in the previous two dialogs, the final dialog presents the data simulation<br />
