How are sexual reproduction and asexual reproduction different from each other?

• sexual reproduction requires two parents and asexual reproduction requires only one parent

• asexual reproduction requires two parents and sexual reproduction requires only one parent

• mutation rates are lower in sexual reproduction than in asexual reproduction

• asexual reproduction occurs only in multicellular organisms
