Extracted text: 2. Read the scenario presented below. Answer the follow-up questions using the information here. Background: Most fruit flies are identical, with yellow-brown bodies, red eyes, and straight wings, but occasionally a different looking fly will hatch. You have identified an unusual fly – one with brown eyes. It is pure-bred. You want to know whether brown eyes are dominant over or recessive to red eyes. Experiment: You cross a purehred brown-eyed fly with a purebred red-eyed fly. All, or 100%, of the offspring have red eyes. Then you take two of these offspring with red eyes, cross them and get 75% red eyes and 25% brown eyes. (adapted from Şavas-Miller and Levine)

You may choose your own letter to represent your allele. (Level 7-8) *hint: use the "draw" tool in Microsoft Word. Be sure to show all work to gain full points.
