Asexual:
- allows for a quick "doubling" of populations (faster)
- less energy required for reproduction
- daughter offspring look exactly and have the same genetic material as the parent
- lack of genetic variation
- population may go extinct with dramatic changes in environment
Sexual:
- allows for genetic variation due to the joining of two different individuals (VERY important for humans)
- less population growth
- slower process
- requires long-term energy use
hope this helps :)

Asexual reproduction requires only one parent, it doubles itself and the daughter organism is exactly the same as the parent individual.. they have the same genetic make up they're pretty much the same,, its like when u make a photcopy of something..
Sexual reproduction requires two parents, gametes are used.. the process is slower n generally takes a longer time, the individual formed is new and has genetic information from both the father n the mother..
pretty much tats all i got.. not too sure about disadvantages n advantages..
