- Genotype of parents: AaBb (wingless, red eyes) x AaBb (wingless, red eyes)
- Possible gametes using the FOIL method: AB, Ab, aB, ab
- Punnett Square:
| | AB | Ab | aB | ab |
|-------|-------|-------|-------|-------|
|
AB| AABB | AABb | AaBB | AaBb |
|
Ab| AABb | AAbb | AaBb | Aabb |
|
aB| AaBB | AaBb | aaBB | aaBb |
|
ab| AaBb | Aabb | aaBb | aabb |
- Trait expected for offspring to have wings and red eyes: Winged, red eyes (genotype: aaB_)
- Trait expected for offspring to have wings and have sepia eyes: Winged, sepia eyes (genotype: aabb)
- Genotype expected to have Aabb: Offspring with genotype Aabb (wingless, sepia eyes)
