As you can see, all but one of these is a Gender exclusive evolution.

Btw it is possible in Swsh to turn a male Salandit/Combee into a Salazzle/Vespiquen, but the game is hardwired to make Salazzle/Vespiquen always female, so the end result will be a gender swap.

As for form changes, Ash Greninja’s gender ratio doesn’t actually change, it’s just that the only one in the whole series is locked to be Male, (probably because Ash’s Greninja is a dude.) No other Pokemons form change causes a gender ratio change. Also, most of the Pokemon who have different forms are legendaries who don’t have genders usually.
