>>32723337The gender ratio was implemented to make it more difficult to breed rare starters. But they also made Ditto a copying machine, so it was kind of pointless in the first place.
Pokemon genders, are, for the most part, aesthetic. It just doesn't feel right when your Sylveon is a male.
It would be worthwhile if genders affected stats. Like all males have a 10% increase in Attack, Special Attack, & Speed while females had a 10% increase in HP, Defense, & Special Defense.
In my headcanon, female starters are rare because the nurseries vet Pokemon that are to be distributed by professors. Nurseries need more females than males, so they keep most of the females. The daycare even examines eggs of starters & withhold the eggs that will hatch female. Of course, they cannot keep all the females, & some Pokemon they cannot tell the gender upon hatching so those hatchlings go to professors.
