Introduced populations of weeds which are polyploid and reproduce primarily by apomixis are generally considered as having low levels of population genetic variation, highly differentiated populations and short evolutionary lifespans. Although polyploidy allows for habitat differentiation and colonization, lack of recombination because of apomixis means that long-term persistence is unlikely. However, variation can be introduced to a colonizing population by evolutionary changes in the mating… CONTINUE READING
