Additionally, another point to prove that bestial races CAN in fact be dragonborn, is that all men, mer, and beastfolk, when killed and soultrapped, have black souls. This proves that, at least metaphysically, all races are on a level playing field when it comes to being able to become dragonborn.

Also, dragonblood is passed on, not being dragonborn because, unless hinduism is a valid belief in Tamriel, souls cannot be passed on to offspring (Unless we want to get technical and argue about someone inheiriting a filled soulgem), and if I am correct, when you are dragonborn, you have to be born with the 'Soul of a Dragon.'

Finally, I am not disputing that it is very likely that Bethesda intends for the dragonborn to nord in cannon, but the purpose of this discussion was to discuss 'How can bestial races be dragonborn?', not 'Could the dragonborn of skyrim be a member of one of the bestial races, and if so how?'

P.S. Nowhere does it say that in order to be dragonborn, you have to inheirit it from a prior line of dragonborn/dragonblood. So stop trying to make connections between the skyrim Dragonborn and Tiber Septim. (Also, the Dragonborn in Skyrim is confirmed to be the Last dragonborn by Miraak if I am correct).
