Final answer:
The reciprocal cross to a cross between a white-eyed female fruit fly and a red-eyed male would be a cross between a red-eyed female fruit fly and a white-eyed male. All the offspring in the F1 generation of this cross would have red eyes.
Step-by-step explanation:
The reciprocal cross to a cross between a white-eyed female fruit fly and a red-eyed male would be a cross between a red-eyed female fruit fly and a white-eyed male. In this cross, the male parent would have white eyes and the female parent would have red eyes. The outcome of this cross would be the same as the original cross: all the offspring in the F1 generation would have red eyes.
