This is not intended to be an impertinent or sacrilegious question. Assuming Jesus was the son of God, and conceived without earthly insemination, why would he necessarily be genetically similar or identical to the Jewish population of the area? In other words, he could have looked entirely different from the typical Nazarene.
I don’t think He could have looked too different from the typical Nazarene. That would have drawn attention to Him in and of itself. The Bible says something about how He had no special beauty to draw people to Him, and I’m thinking He had no special ugliness, either. People were not going to be drawn to Him based on how he looked, one way or the other.
Just my thoughts; could be totally wrong. :-)
