Question

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?

Answer 1

WW | Ww | wW | ww. The (W) is the most dominant and while the (w) is the least. 3 if them are dominant which is 75%, on the other hand, 1 is (w,w) which is curly wings and it equals to 25%. So, I think the answer is 25% will have curly wings.

Hope I helped☺☺
