Some fruit flies are born with curly wings which makes them unable to fly. It has been shown that curly wings are caused by a dominant gene which can be represented by the symbol W, while the recessive normal wing gene is represented by the symbol w. If a parent fly with the genotype WW is crossed with a parent of the genotype Ww, what percentage the offspring will have curly wings?

Hey mate!!
_________________________________________
it is mentioned in question that
DOMINANT GENOTYPE IS W
and that of RECESSIVE IS w
now, by crossing them in F1 generation we get,
WW x Ww
→ WW Ww. WW. Ww
since, W is dominant over w
and it is autosomal dominant
so, all progeny have Curly Wings.
so, there is 100% chance of having Curly wings.
hope it helps!!
