Asexual reproduction yields genetically-identical organisms because an individual reproduces without another. In sexual reproduction, the genetic material of two individuals from the same species combines to produce genetically-different offspring; this ensures mixing of the gene pool of the species.
FOR EXAMPLE:
Let's say you've been taking melatonin every single night to help you sleep. After a while, you may notice that it begins to take more and more melatonin for it to work like it did the first night you took it.
