AP 15-16 Test Review When Thomas Hunt Morgan crossed his red
... When Thomas Hunt Morgan crossed his red–eyed F1 generation flies to each other, the F2 generation included both red–and white–eyed flies. Remarkably, all the white–eyed flies were male. What was the explanation for this result? Which of the following is the meaning of the chromosome theory of inheri ...
