In 1927, the geneticist Hermann Muller exposed living fruit flies to X-rays. He found that the fruit flies' offspring displayed dramatic mutations. Muller concluded that the X-rays damaged chromosomes. What was the independent variable in Muller's experiment?
- A.
The X-rays
- B.
The fruit flies
- C.
The mutations
- D.
The chromosomes
Correct Answer
A. The X-raysExplanation
In Muller's experiment, the independent variable is the X-rays. This is because the X-rays were deliberately manipulated and controlled by Muller in order to observe their effects on the fruit flies and their offspring. The independent variable is the factor that is changed or manipulated by the researcher in an experiment to see its impact on the dependent variable, which in this case would be the mutations observed in the fruit flies' offspring.Rate this question:
