sexual reproduction produces offspring with genetic material from both parents & a crop of corn plants is genetically modified to produce a natural pesticide & corn plants reproduce through sexual reproduction ->  sexual reproduction between genetically modified corn plants produces offspring with genetic material that produces a natural pesticide  if something required for a process is not produced then that process is prevented from occurring / cannot occur & reproduction of the plants often requires pollen ->  if pollen is not produced then plant reproduction is prevented from occuring  if pollen is not produced then plant reproduction is prevented from occuring & corn is a kind of plant ->  if the corn does not produce pollen, then the corn reproduction is prevented from occuring  sexual reproduction between genetically modified corn plants produces offspring with genetic material that produces a natural pesticide & if the corn does not produce pollen, then the corn reproduction is prevented from occuring -> if pollen is not produced then genetically modified corn plants will be prevented from producing offspring with their genetic material
