A Gender determines whether the Pokémon is male or female in the Pokémon video games. Some Pokémon have a greater chance of being one gender than another, such as Blastoise which has a 87.5% chance of being male, but only a 12.5% chance of being female. There is also moves that will only work when Pokémon are certain genders. There were no genders in the Generation I games.
