A scientist studying Drоsоphilа received three different mutаnts thаt all had tiny wings. When flies with the r1 mutatiоn were crossed with flies with the r2 mutation, all offspring had wild-type wing size. When flies with the r1 mutation were crossed with flies with the r3 mutation, all offspring had wild-type wing size. What wing size would you expect if the scientist crossed flies with the r2 mutation with flies with the r3 mutation, and why?
