60. When a white eye Drosophila male (X' Y) is crossed to a red eye female (X* X"), in the F2 generation all the females are red eyed and 50% males are white eyed. In a criss cross test, when a white eyed female (X' X)is crossed to a red eye male (X* Y), the Fi generation off spring had white eyed males while the female offspring had red eyes. Instead of crossing of a white eyed female (X' X) to a red eyed male (X*Y), white eye female (X' X) to white eye male (X'Y) is crossed, the F1 generation will have the following phenotypes and genotype. (1) All females have white eye (X'X', X' X) and all males have red eye (XY, X'Y) (2) All females have white eye (X'X', X'X') and 50% males have red eye (X* Y, X'Y) (3) 50% females have white eye (X' X', X*x) and all males have white eye (X Y, X'Y) (4) All females have white eye (X'Y', X'X) andall males have white eye (X' Y, XY)

60. When a white eye Drosophila male (X Y) is crossed to a red eye female (X X"), in the F2 generation all the females are red eyed and 50% males are white eyed. In a criss cross test, when a white eyed female (X' X') is crossed to a red eye male (X* Y), the Fi generation off spring had white eyed males while the female offspring had red eyes. Instead of crossing of a white eyed female (X' X) to a red eyed male (X*Y), white eye female (X' X) to white eye male (X' Y) is crossed, the Fi generation will have the following phenotypes and genotype. (1) All females have white eye (X'X', X'X') and all males have red eye (XY, X'Y) (2) All females have white eye (x'X", X'X) and 50% males have red eye (X Y, X'Y) (3) 50% females have white eye (X' X', X* X') and all males have white eye (X Y, X'Y) (4) All females have white eye (X'Y', X'X) and all males have white eye (X' Y, X'Y)
