>>41520151The way Pokemon genetics works is that a child is always completely 1 species, but can potentially express traits of the other parent. Assuming a male human and female Pokemon, the child would almost certainly be the species of the mother, and the child would be human for a female human impregnated by a male Pokemon.
I can't imagine what traits a human would pass to a Pokemon, but since Human genetics allows physical traits to pass on, an Arcanine father could give its human child orange hair or something.
However, let's say for the sake of fantasy that humans are special and Pokemon females can bear human children to human males (we could argue that this is due to human genetics being so different to Pokemon ones.) A child born from a Pokemon could have the same sort of Pokemon features as the children of a Pokemon father: the child of your Gardevoir could have green hair and weak empathic abilities.
The real problem with deciding how Pokemon bearing human children is that Pokemon do not give birth the same way. They don't seem to have pregnancies like humans, either. Do they lay the human child in an egg, or do they have wombs that can accommodate human pregnancies just in case? There IS the canon tidbit about Eggs not being "real" and instead just being magical cradles the babies are stored in, so Pokemon could also potentially just magically poof the developed human fetus into one of their Birthing Eggs that stores it in stasis until it's hatched.
