Asexual reproduction:
One advantage is that many offsprings are created within only one parent.
Another advantage is that the offspring obtains the characteristics of their parent
A disadvantage is that they will not be able to adapt to the environment because they have the same characteristics as their parents
Another disadvantage for asexual reproduction is that there is no mate. Only one parent creates an offspring
Sexual Reproduction:
One advantage is that unique offspring are created and have better traits in where they can survive in the environment.
Another advantage is that it contributes to two parents
A disadvantage for sexual reproduction is that it can prevent favorable genes from being passed on to offspring
Another disadvantage is that it requires two parents and for the fact that this takes time and energy.
Hope this helps! :)
