Pokémon from the Generation I games are assigned a gender using the same process when transferred to the Generation II games, used in Pokémon Stadium 2, or transferred from the Virtual Console games to Pokémon Bank. Starter Pokémon and others with a gender ratio of seven males to one female suffer the most, with the maximum physical Attack IV for a female Pokémon of those species being 1.

A Pokémon is female if its physical Attack IV is less than or equal to its species' gender ratio, otherwise it is male. In Generation II, a Pokémon's gender is determined based solely on its physical Attack IV when compared to its gender ratio.
