Higher organisms have resorted to sexual reproduction in spite of its complexity. Why?
Although sexual
reproduction involves more time and energy, higher organisms have
resorted to sexual reproduction in spite of its complexity. This is
because this mode of reproduction helps introduce new variations in
progenies through the combination of the DNA from two (usually)
different individuals. These variations allow the individual to cope
with various environmental conditions and thus, make the organism
better suited for the environment. Variations also lead to the
evolution of better organisms and therefore, provide better chances
of survival. On the other hand, asexual reproduction does not provide
genetic differences in the individuals produced.
