In Thomas Hunt Morgan's experiments, the ratio of red-eyed flies to white-eyed flies appeared to follow a simple Mendelian pattern of inheritance. What observation(s) did he make that led to his conclusion that the white-eyed trait was actually not a simple Mendelian trait?
A. He was able to correlate the expression of white eyes to the inheritance of an X chromosome. B. He was able to correlate the expression of white eyes to the inheritance of an X chromosome because only F2 males had white eyes and the trait is recessive. C. He saw that only males had white eyes. D. He observed that the white-eyed trait was recessive. E. He was able to correlate the expression of white eyes to the inheritance of a Y chromosome because only F2 males had white eyes and the trait is recessive.
