What was the result when morgan mated a white-eyed male fruit fly with a red-eyed female fruit fly?
a. half the offspring had white eyes.
b. all the offspring had white eyes.
c. all the offspring had red eyes.
d. only male offspring had red eyes.

The answer is C since I’m assuming that Red is dominate than white

The correct answer is option A-half the offspring had white eyes.

Explanation:

Thomas Hunt Morgan performed a classic experiment on Drosophila melanogaster in 1910.  

He performed an experiment by crossing the white-eyed male with red-eyed female and found that in F₁ generation has all the red-eyed fruit fly which were crossed again with white-eyed male and he found that female had red eyes and males have white eyes out of which half of the male were red-eyed and white-eyed.

Thus, option A is the correct answer.

community
