Question

A plant may have green, white, green and white(variegated) leaves on its branches, owing to a mutation in the chloroplast that prevents color from developing. predict the results of the following crosses. show work

Ovule source Pollen source

Green branch x White branch
White branch x Green branch
Variegated branch x Green branch
Green branch x Variegated branch

Answer 1

GG= green, gg=white, Gg= variegated (Codominance)

1)GG*gg=Gg,Gg,Gg,Gg
2)gg*GG=same sh!t
3)Gg*GG=GG,GG,Gg,Gg
4)GG*Gg=GG,Gg,GG,Gg

This is all assuming that variegation is caused by codominance. If it is cause by an autosomal recessive mutation then the only time that variegation occurs will be when you have two g's together.
