Editing Alternation of generations (section)

=== Animals ===
Alternation between a multicellular diploid and a multicellular haploid generation is never encountered in animals.<ref name="Barnes-2001">{{Harvnb|Barnes|Calow|Olive|Golding|2001|p=321}}</ref> In some animals, there is an alternation between [[parthenogenesis|parthenogenic]] and [[sexual reproduction|sexually reproductive]] phases ([[heterogamy]]), for instance in [[salp]]s and [[Doliolida|doliolids]] (class [[Thaliacea]]). Both phases are diploid. This has sometimes been called "alternation of generations",<ref name="Scott-1996">{{Harvnb|Scott|1996|p=35}}</ref> but is quite different. In some other animals, such as [[hymenoptera]]ns, males are haploid and females diploid, but this is always the case rather than there being an alternation between distinct generations.
