Farmer Brown grows corn for a living. One day, Farmer Green suggests to Farmer Brown that he should clone his best corn plant in order to produce more ears of corn per plant. Farmer Brown is not sure about Farmer Green's idea. Why might Farmer Brown be hesitant to clone his corn?

Farmer Brown might be hesitant to clone his corn because cloning eliminates the ability to sexually reproduce and provide genetic variability. There will be no variability in genes in these clones, because given that they are exact copies of their "parent," they will all be identical, without any difference or variation. This farmer doesn't want that to happen, which is why he is hesitant to take Farmer Green's advice.
