Extra info on The wings of fruit fly:

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, 100% of the offspring will have curly wings.
