In fruit flies, the following X-linked traits are found: whiteeyes are recessive to red eyes, ebony body is recessive to graybody, and short wings is recessive to long wings. A cross was madebetween wild-type males with red eyes, long wings, and gray bodiesand females with white eyes, short wings, and ebony bodies. Femaleheterozygote resulting from this cross, which had red eyes, longwings, and gray bodies, were then crossed with males with whiteeyes, short wings, and ebony bodies. The F2 generation data isobtained below:
