What will be the result of the first filial generation (F₁) and the second filial generation (F₂) of a mono-hybrid cross between pure line normal-winged Drosophilia flies and pure line short-winged flies, if the gene for the normal wing is dominant?

F₁ flies all short-winged and F₂ flies all normal-winged

F₁ flies all normal and F₂ flies all short-winged

F₁ flies all short-winged and three-quarters of F₂ flies are short-winged

F₁ flies all normal-winged and three-quarters of F₂ flies are normal-winged
