Changes

Among those elements are [[MPREG]], [[going into heat]], a hierarchical biology-based class/caste system, and [[knotting]]. Other tropes dealing with "a basic biology they cannot deny" include [[pon farr]], the [[Sime~Gen]] universe, and some elements of [[Sentinel AU]].

According to one commentator on [[FFA]], A/B/O fic can be distinguished from earlier tropes by its combination of biological changes with a culture structured around the differentiated biology: {{Quotation|I always say it's the class system based on biological characteristiques and knotting, though other nonnies have pointed out that knotting isn't omnipresent in fic being written nowadays. Mpreg isn't so much needed as the possibility of mpreg - and someone may write fic where alphas and omegas are biological dead ends and thus remove the possibility of mpreg and thus remove that possibility and I, personally, would still consider it a/b/o as long as they'd be a differentiated social group. The same rational goes for heats, as long as other biological markers are in place to account for the biological part of the genre. It's the the articulation between those differences and the social [side] of things that is really the indispensable part.<ref>{{source| url = http://fail-fandomanon.dreamwidth.org/185139.html?thread=1008892979#cmt1008892979 | title = fail_fandomanon | FFA DW Post # 383 - Greek social fallacies |archiveurl= http://www.webcitation.org/6fiuuE4y7 |archivedate= 2016-03-03 }}</ref>}}

A similar premise was used in [[Life from the Ashes]] in [[X-Files]] fandom in the 1990s. In that story, a virus biologically changes half of the male population into breeding partners who emit sex pheromones. Social differentiation between the biologically determined groups is not explicit, although by the end of the story, it is implied.
