P.S. I know of conduction range tops (an idea which I don't like, but I have no experience with the real thing). Are they making conduction ovens also? Seems like a particularly dumb idea to me if they are. -I've been into electronics since I was young and was radio repair in the Army, so while I have no experience with conduction ranges I know how they work.
I always thought all range tops are considered "conduction" deveices, as are all non-fan ovens. But with a gas appliance there is always a significant amount of convection because of the flow created by the constant stream of combustion gases. But true convenction I believe implies a "bulk" fluid flow, such as a fan provides.
this also makes gas an "open system," where you have the hot combustion constantly flowing out of the oven and, unless having a vent that exits the building, they simply dump into the room, for your air conditioner to work overtime on. Much the same for gas range tops.
Non-fan electric ovens are almost pure conduction, where most of the heat is transfered by its slow diffusion through the air in the oven, along with direct infra-red radiation from the heaters (the cause of "hot spots"), and some very little convection by the gravity initiated flow of air, ie, hot air rises and upon cooling sinks again. This gravity feed is so insufficient though that large electric ovens absolutely require a fan to make them work adequately, so I have heard and it making perfect sense. They are essentially a "closed system" and give off relatively little heat. Same for modern glass-top electric ranges, very little waist heat at point-of-use (lots of waist heat in electric generation and transmision of course).
Still I don't doubt the possibility a gas convection oven cooks better than and electric convection, so out of curiousity I'll check with some manufacturers next week and see if they can clear this up.

Wait a minute, either you ment induction rather than conduction, or your taking advantage of the autistic kid's limited abilities with inuendo. ;-)~
