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?

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?
A) 100%
B) 75%
C) 50%

D) 25%

Answer 1

A

Step-by-step explanation:

100% is the answer

Answer 2

It would be 100%. As you can see in my punnet square, there are no boxes with ww, which means that ll of the flies would have curled wings. (this is because you have to have two recessive genes for that gene to show)
So it would be A. 100%
