A benefit of sexual reproduction is

• less energy is used

• greater genetic diversity in the species

• it is more efficient than asexual reproduction

A disadvantage of sexual reproduction is that it is

• more time consuming than asexual reproduction

• creates less diversity than asexual reproduction

• uses less energy than asexual reproduction
