- In Corn, Male sterility is controlled by maternal cytoplasmic elements. This phenotype renders the male part of corn plants(i.e. the tassol) unable to produce fertile pollen; the female parts. However, remain receptive to pollination by pollen from male fertile corn plants, however the presence of a nuclear fertility restore gene F restores fertility to make sterile lines. b.
