>>34765198You realize that about 90% of Pokémon that appear in the anime don't have a confirmed gender right? That's just you expecting species completely different from humans to act like humans because the series is made by humans, even though that would make no sense both in and out of universe.
And on the breeding thing, it'd just be a huge plot hole to have like 70% of the species have heavily skewed ratios towards being male and still be plentiful in the wild.
