Step 2: Hypothesize
Fruit flies can have wing shapes that are different from the normal (or "wildtype") straight wings of most flies. One of those traits is called "curly", which causes the wings to curl upward. Flies with this trait cannot actually fly, but instead hop around to move. Scientists are not 100% sure how this trait is inherited, although several experiments have suggested that it is dominant.
In order to test the inheritance of the curly trait for ourselves, we will be crossing wildtype females with curly males. In order to best come up with your hypothesis, answer the questions below. Please note that although here a letter has been used to represent the wildtype genotype, in the research community wildtype flies are represented by "+" symbols.
