In plants,cytoplasmic male sterility (CMS)is maternally inherited due to mutations in mitochondria.However,these can revert to normal due to a nuclear gene for restoration of fertility (RF).The recessive rf/rf condition does not restore fertility.If the female parent of a male plant is CMS rf/rf and the male parent is normal (N)Rf/Rf,will male progeny be sterile or fertile?
