Reproduction in animals varies from species to species. Some types of reproduction, like parthenogenesis, are more unusual ...

Coprinus cinereus also produces spores by asexual reproduction. These spores can be produced quickly and in large numbers to enable many individual fungi to develop. A disadvantage of these spores ...
