Both mitochondria and chloroplast are maternally inherited. Some plants develop resistance to atrazine herbicide through a mutation of a gene located in the chloroplast. If male plants without any such herbicide resistance are crossed with an atrazine resistant female plant, what will be the resistance level of offspring plants? A) All offspring will be resistant. B) None of them will be resistant. C) Half will be resistant and half susceptible. D) Only the female plants will be resistant and not the male plants. E) Only the male plants will be resistant and not the female.

A) All offspring will be resistant.
