Ascientist is studying fruit fly wings. straight wings are dominant, and curly wings are recessive. which statement correctly describes the f1 generation if a straight-winged parent is crossed with a curly-winged parent and if both paremts are true breeding?

The answer is 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 - straight-winged parent
aa - curly-winged parent

In their cross:
Parental generation:     AA     x      aa
F1 generation:           Aa    Aa    Aa     Aa

So, the offspring have one allele for straight wings and one allele for curly wings.
