Answer:
The correct options are: A "
vestigial wings, red eyes" and D "full wings, purple eyes"
Explanation:
female parent: vg+pr+/vg pr
(phenotype - full winged and red eyes)
male parent: vgpr/vgpr
(phenotype - vestigial winged and purple eyes)
Of these traits, vestigial wings and purple eyes are recessive traits. Hence, when a recombination event occurs, the offspring can potentially have a wild type trait paired with a recessive trait.
B - They have different arrangements of atoms.
