Solution

The correct option is C
Dominant over

Morgan started his work with the fruit fly around the year 1904. He was breeding fruit flies for his research. Normally in Drosophila, the color of the eye is red. Thomas Hunt Morgan, studying the fruit fly Drosophila melanogaster, detected a mutant male fly, one that differed strikingly from normal flies of the same species: its eyes were white instead of red. He first crossed the mutant male to a normal female to see if red or white eyes were dominant. All of the $F_{1}$ progeny had red eyes, so Morgan concluded that red eye color was dominant over white.
