Gender
Gender is male, female or genderless, set per individual from a species-wide ratio
Gold and Silver added gender so that breeding could work. Species have fixed ratios such as 87.5 percent male for most starters, 50 percent for many species, and genderless for Magnemite and most legendary Pokémon. In Generation II gender came from the Attack DV, so females of male-leaning species had lower Attack.
