Heatran ARE supposed to have genders. It's how they are in the official games. It's just that, in spite of them having genders, they can't breed, given that they're legendaries. Nobody knows why GameFreak bothered to let Heatran be male or female when they haven't done this with any other legendary (sure, Latios, Tornadus, Thundurus, and Landorus are male, and Latias and Cresselia are female, but none of them can be either gender like Heatran). All we know is, they have genders and they can't breed.
