what are advantages and disadvantages of sexual and asexual mode of reproduction

The advantages of Asexual Reproduction are:

• It is a faster means of reproduction  
• Less energy required for reproduction
• Number of progeny produced is more

The disadvantage of Asexual Reproduction is:

• The daughter offspring look exactly and have the same genetic material as the parent
  lack of genetic variation. So as a result the population may go extinct with dramatic changes in environment.

 

The advantage of Sexual Reproduction is:

• It allows for genetic variation due to the involvement of two parents
  
  

The advantages of Sexual Reproduction are:

• It is a slower process
  
  
• It  requires more energy 
• Lesser number of progeny can be produced at a time
