I have looked at the following relationships in the
A. I54 -> I2348
B. I2348 -> I54
C. I87 -> I2348
D. I2348 -> I87
I54 and I87 are cousins.
So would expect that A. and C. (and B. and D.) to show
a similar path through grandmother I63.
I would also expect A. and B. to show similar paths only
in opposite directions.
PGV does not create relationship paths based on the
above 2 assumptions.
