>believing games gender ratiosTake ralts line for an example:
All ralts, kirlia, gardevoir and gallade are born ralts. Ralts have a 50% chance to be born male, and a 50% to be female. Every kirlia evolved from ralts, so you can expect it to be 50/50 once again, but now something weird happens: a female kirlia can only evolve into a gardevoir, but males can become a gallade. So if you take a population of kirlia, composed by a 50% of males and females, assuming all will evolve eventually, you'll be left with at least 50% female gardevoir, at least 1 gallade (otherwise the pokemon wouldn't exist in the first place), and a <50% male gardevoir. This last percentage could also be a 25%, that is not known.
Despite this, the game states gardevoir to be a 50% male to female ratio. Don't fixate on game stats because they're not so well thought as you'd think
