The answer is <span>The offspring will have one allele for straight wings and one allele for curly wings.
If:
A - dominant allele for straight wings
a - recessive allele for curly wings
Then:
AA - </span><span>straight-winged parent
aa - </span><span>curly-winged parent
In their cross:
Parental generation: AA x aa
F1 generation: Aa Aa Aa Aa
So, the offspring have one </span><span>allele for straight wings and one allele for curly wings.</span>
