3. I think its still possible there is a smaller male just not in game much like other breeding habits, Subspecies and variations of monsters.

Some examples of breeding info that doesn't show up in the games are Kutku grows a bunch of vibrant feathers when breeding, Khezu injects its young into paralyzed prey, Zinogre live in huge herds and take care of their young, Duramboros do the same as Zinogre, Barioth have a bunch of cat like kittens they care for as a pair and we didn't even know Black Diablos was female during her first appearance so the game just came out we would need to wait for more info.
