Sexual and Asexual Reproduction Compared
Captions available
The idea
Asexual reproduction, such as prokaryotic binary fission, produces genetically identical offspring from one parent; sexual reproduction combines gametes from two parents, producing varied offspring.
In practice
A bacterium dividing by binary fission produces a clone, while two parents producing offspring by meiosis and fertilization produce genetically distinct young.
Where people slip
Sexual reproduction's advantage is variation, not efficiency — asexual reproduction propagates a population faster per generation.
