Sexual reproduction has many benefits from a genetic standpoint. Can you think of any downside to sexual
reproduction? What will be an ideal response?
ANSWER: The most obvious downside of sexual reproduction is that it requires another member of the
same species. For organisms that are widely dispersed, this could be difficult. Second, it
requires that the other member of the same species be willing to mate. For many organisms,
this is a great challenge. Lastly, it does mean that only half the genes can be passed on.
Thus, the imaginary ‘perfect' member of the species would see its offspring doomed to
imperfection by the input of genes from another. All this being said, sexual reproduction is
clearly a very efficient and effective means of reproduction.
