Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Drosophila melanogaster (fruit fly) is widely used in genetics due to several advantageous features.
Step 1: Analyze each statement.
• A → Male and female flies are easily distinguishable $\Rightarrow$ Correct
• B → Life cycle is about 2 weeks, not 3 weeks $\Rightarrow$ Incorrect
• C → Produces large number of offspring $\Rightarrow$ Correct
• D → Phenotypic traits are easily observable $\Rightarrow$ Correct
Step 2: Select correct combination.
Correct statements are: \[ A,\ C,\ D \]
Step 3: Final conclusion.
Thus, the correct option is: \[ (C) A, C and D only \]
