Describe the advantages and disadvantages of asexual reproduction and sexual reproduction. Provide three examples of animals that engage in each type of reproduction.
define asexual reproduction and describe two methods of asexual reproduction in animals
Asexual reproduction passes on 100% of the parent's genes but it is relatively rare.
What are the advantages of sexual vs asexual reproduction? In some cases, species
are hermaphrodites to reduce the difficulty in finding mates. What is the difference
between simultaneous and sequential hermaphrodites? Why is "selfing" relatively
rare?
