WHAT IS IT?

This is an inheritance model of genetic linkage, including both X-linkage and autosomal linkage.

HOW TO USE

  1. Select one of five cases
  2. Click on the "Start/reset" button to start or start over .
  3. Click on the "Press and choose 2 parent flies" button.
  4. Choose a male and a female in the simulation window. The males are smaller and have a dark abdomen tip.
  5. Click on the "cross!" button to conduct a test cross.
  6. Examine offspring phenotypes in the simulation window and the "progeny" section.
