What is the difference between sexual and asexual reproduction?
At the most basic level, sexual reproduction involves the fusion
of gametes (sperm and egg in animals) to form a zygote
(fertilized egg). Asexual reproduction involves multiplication
by simple division (for example, budding). The result of sexual
reproduction is a unique offspring different from either parent.
The result of asexual reproduction is offspring identical to the
parent (and to each other). Some organisms reproduce exclusively
by sexual reproduction. Some reproduce almost exclusively by
asexual means. However, some degree of sexual reproduction is
desirable because it helps to generate genetic diversity in the
species. Click here to return to the Biology Archives Update:
