Uh oh... I would say probably not theres the true Dragonborns like our character in Skyrim, Tiber Septim and for some reason Miraak, they were gifted the blood and soul of a dragon by Akatosh. Then theres the dragon blood emperors like Uriel and the other Septims they got some sort of power (to wear the amulet of kings and light the dragonfires) from inheriting the blood but not the ability to absorb souls and the affinity for the thu'um.

You don't pass your soul on to your children and being Dragonborn is a rare gift from a god if it was passed down it would be that rare.

Maybe Uriel Septim was a chosen of Akatosh who knows, but i don't think being a descendant automatically makes you truly Dragonborn. Other people would say yes it would though.
