Question

The normal blue petal color in the blue - eyed Mary depends on two genes, W and M. mm plants accumulate a magenta intermediate in synthesis of the blue pigment. WW plants are blocked earlier in the pathway, cannot make the magenta compound, and have white petals. A cross between homozygous white and magenta lines produce a blue F1. What types are expected in the F2 when the F1 are selfed? Another homozygous white line was crossed to the same magenta line, but produced a magenta F1. What types are expected in the F2 when these F1 magenta are selfed? One magenta plant from the F2 of part B produced only magenta F3 when selfed, but another yield both magenta and white. Explain how these two F2 magenta plants differed.
