Bioscience in brief
Plant genetics and crop breeding
How do plants reproduce sexually?
Each kernel in a cob of maize is the seed of a new individual, and although they all share a mother, they can each potentially have a different father. For this reason plant breeders need to protect the ears (the female inflorescence of maize) after a breeding cross, to make sure the female parent is only exposed to the pollen of the chosen male parent.
