Question

Which one of the following is dominant among the wing sizes in {Drosophila?

• A. Normal wings
• B. Vestigeal wings
• C. Notched wings
• D. Nicked wings

Hint:

Vestigial wings are a commonly studied recessive mutation in fruit flies.

Answer 1

The Correct Option is A

Step 1: Understanding Mendelian traits in {Drosophila. Wing size in {Drosophila melanogaster} is a classical example used in genetic studies.
Step 2: Dominant and recessive traits.
Normal wings are dominant, whereas vestigial, notched, and nicked wings are mutant recessive traits.
Step 3: Conclusion.
Therefore, the dominant wing type in {Drosophila} is Normal wings.
