Question

Match the correct phenotype and genotype of {Drosophila for their wing sizes. Phenotype Genotype
(i) Normal wings a) vg$^{no}$
(ii) Nicked wings b) vg
(iii) Notched wings c) Vg$^{+}$
(iv) Strap wings d) vg$^{st}$
(v) Vestigial wing e) vg$^{ni}$

• A. (i)–e, (ii)–d, (iii)–c, (iv)–b, (v)–a
• B. (i)–a, (ii)–b, (iii)–c, (iv)–d, (v)–e
• C. (i)–d, (ii)–a, (iii)–b, (iv)–e, (v)–c
• D. (i)–c, (ii)–e, (iii)–a, (iv)–d, (v)–b

Hint:

{Vg$^{+}$ = normal wings; vg = vestigial wings}.

Answer 1

The Correct Option is D

Step 1: Understanding wing mutations in {Drosophila. Different wing shapes in {Drosophila} are caused by mutations in the vestigial (vg) gene.

Step 2: Correct matching.
Normal wings correspond to wild type genotype Vg$^{+}$.
Nicked wings are due to vg$^{ni}$.
Notched wings correspond to vg$^{no}$.
Strap wings correspond to vg$^{st}$.
Vestigial wings correspond to vg.

Step 3: Conclusion.
Thus, the correct matching is option (D).
