→Trivia: Since the Generation is over now.
* Generation VII added the most genderless Pokémon, with a
current total of 27.
* Prior to [[Generation VI]], because Azurill's gender ratio does not match that of its evolved forms and its evolution is not dependent on gender, being female 75% of the time while Marill and Azumarill are female only 50% of the time, female Azurill has a 1/3 chance of evolving into a male Marill (depending on its [[personality value]]). Azurill is the only Pokémon to do this. From Generation VI on, Azurill retains its gender upon evolving, despite the gender ratios still differing.
