son 1 - gets eye power
son 2 - gets body power
son 1 got the rinnegan but his kids and so on and so fourth got the mutated less powerful sharingan somehow it evolved..
Nagato must have been A DIRECT descendant of the first son and got lucky i guess.. the other got the second rate eye power.. more of that will be explained..
we don't even know if madara's lying or not.
