Step 1: Select Your Cross!
The fruit fly is one of the most studied organisms in genetics research. Almost a third of known human diseases have a match in fruit flies, and over half their proteins are similar to ours (NASA has more to say on this subject). That's why studying patterns of inheritance of certain fruit fly traits can be so valuable to humans. They're also great for genetics studies because fruit fly mutations are often easily observed. In other words, many mutations will affect something visible like eye color, body color, wing shape, or body shape. When you complete your cross below, keep in mind how difficult it would be to analyze your results if you couldn't see the trait!
