Thats just it though, Asura does not have all his fathers genes and neither does Indra. No one has every gene from ONE parent when born, a child is born with genetic makeup of the mother and the father with traits being dominate over the over and a probability chance of retaining a specific trait. We can assume Asura and Indra's mother was a normal human and the half her genes makes up their traits too. The chance Asura gaining sharingan when born is a 1/4 chances and lucked out.
