A)polyploidy.
B)allopatrism.
C)coevolution.
D)sympatric speciation.

A farmer sprays a field with an herbicide that kills most of the weeds he finds. Could the weeds develop resistance to the herbicide over the course of a growing season?

A)Yes; the herbicide will induce mutations that create resistance alleles.
B)Yes; if the weeds have enough genetic variation, they can evolve rapidly through natural selection.
C)No; the process of evolution is very slow. The evolution of herbicide resistance would take thousands of years.
D)No; in order to develop resistance, the weeds would have to hybridize with a plant that is already resistant to the herbicide.
