From the Population Menu, choose a population to investigate. A wild population with at least one segregating trait will be collected if you select a population that has not yet been examined.

Organisms can be crossed by clicking or dragging one male and one female into the crossing box on the right side of the screen. Once two organisms are in the crossing box, click the "Cross" button to create a new generation.

Organisms can be sorted and viewed according to sex, any single trait, or all traits by using the drop-down menus on the top of the vial.

Information about each vial can be found by clicking the "Analysis" button. Notes and vial info can be copied & pasted into a word processor for easy note taking. A Chi squared test can be performed by clicking the "Stats" button and entering an expected ratio.
