Vedclass · Answer

(D) In $Drosophila$,the wild-type allele for wing shape is denoted as $Vg^{+}$.This wild-type allele is dominant over all other mutant alleles (such as $vg^{ni}$,$vg^{no}$,$vg^{st}$,and $vg$).Since all the given genotypes contain at least one $Vg^{+}$ allele,they will all express the dominant wild-type phenotype,which is normal wings.Therefore,all five genotypes represent normal wings in $Drosophila$.

How many of the following genotypes possibly represent normal wings in Drosophila?
$(i)$ $Vg^{+} Vg^{+}$
(ii) $Vg^{+} vg^{ni}$
(iii) $Vg^{+} vg^{no}$
(iv) $Vg^{+} vg^{st}$
$(v)$ $Vg^{+} vg$
