In asexual reproduction, reproductive organs aren't used but they're used.
 
advantage of sexual- A lot of genetic variation. since they have DNA of two parents. they can survive more and adapt more.
disadvantage of asexual- diversity is limited. Since the organism only gets the DNA of one parent, they wouldn't be able to really survive if something happened.They would easily be extinct.
Sorry I can't really cone up with better words but I hope you get the idea. it all comes down to natural selection really if you've learned about it. Hope it helped!!!
