Step 2: Hypothesize
Fruit flies can have many body colors that are different from the normal (or "wildtype") yellow-brown color of most flies. One of those colors is ebony, which is a slightly darker color than the wildtype. Scientists are not 100% sure how this trait is inherited, although several experiments have suggested that it is recessive.
In order to test the inheritance of the ebony trait for ourselves, we will be crossing wildtype females with ebony 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.
