In fruit flies, curved wings are recessive to straight wings, and ebony body is recessive to gray body. A cross was made between flies (all true-breeding) with curved wings and gray bodies to flies with straight wings and ebony bodies. The F1 offspring were then testcrossed to produce an F2 generation. The following data were obtained: F2 generation: -104 curved wings, ebony body -106 curved wings, gray body -98 straight wings, gray body -92 straight wings, ebony body With a null hypothesis based on independent assortment, what are the expected values for each class of flies (400 total flies)
