Advantages:

• Increased genetic variability because of meiosis and genetic recombination
• can exchange genes
  
• Strong evolutionary potential
  
• Adaptation to changing conditions
  
• Successful long-term
  
• May allow plant to live under a wider range of conditions or to grow faster because of greater tolerance

• Can destroy well-adapted genotypes because the offspring (genotypes) from sexual reproduction are not guaranteed to be viable, as is the case with selfing
• Relies on effective cross-pollination, seed dispersal, and establishment
