    What are the advantages and disadvantages of asexual reproduction?

    Advantages:

    Mini-me!


    Disadvantages:

    No fun.

    Seriously...

    Advantages:

    More efficient
    Faster (only requires one individual)

    Disadvantages:

    No scope for genetic change, therefore no possiblity of adaption against threats.

    Another advantage is that certain good features are preserved in the offspring.

    I think he means that sexually reproducing organisms are at an advantage because not all individuals are susceptible to the same 'threats'. Traits are, more often than not, determined and controlled by larges suites of genes - mutation is not (generally, for larger, multicellular organisms) a rapid enough method of allowing adaptation on it's own - meaning that recombination of alleles etc. affords almost infinite scope for change.

    A disadvantage is that if one catches a disease they are all going to get a disease as they are all the same.

    oops thats already been said.

    They will still vary because of mutations, eg. some alpha particles could smash up some DNA and cause the new mutated DNA to produce proteins that are resistant to infections.

    Advantages are... this is not a real life advantage (probably never be used) but if there's only one left, the species will survive. Also I guess it's faster?

    Disadvantages.. maybe less variation than sexual reproduction since there is no mixing of parent genes to make offspring, therefore there are less substantial variations and advantageous variations are less frequent, so evolution is slower.

    Asexual reproduction is far less energetically expensive.

    Another disadvantage no-one seems to have stated is that there will be high levels of competition between the offspring to ensure their survival, since asexual reproduction generally produces large numbers of offspring in a certain area with limited resources.

    This survival competition can lead to the death of large numbers of the offspring. Of course, this could be regarded as an advantage, i.e. since the weaker offspring died, more room was available for the stronger (and better) offspring.

    Am I understanding your post correctly?

    - disadvantage of asexual reproduction is that much competition arises between offspring (such as during binary fission of bacteria etc.)
    - this competition can be advantageous by means of natural selection.

    Are these statements really only applicable to asexual reproduction?

    Not specifically.
