Question

What is the genotype of Drosophila showing normal wings?

• A. vg+
• B. vg no
• C. vg
• D. vg ni

Hint:

In Drosophila, the "vg+" allele is dominant and results in normal wings, while the "vg" allele causes vestigial wings.

Answer 1

The Correct Option is A

In Drosophila, wing shape is governed by the "vg" gene. The "vg+" allele signifies the standard wing morphology, whereas the "vg" allele results in vestigial (abnormal) wings. Consequently, the genotype for normal wings in Drosophila is "vg+", with the "+" denoting the dominant allele for normal wings. - "vg" denotes the recessive allele responsible for vestigial wings. - "vg no" and "vg ni" are not standard genotypes within this framework. Therefore, the correct designation is "vg+".
