Path: You → Mother → Sister → Daughter
Cousin degree equals min(2, 2) − 1 = 1. Removal equals |2 − 2| = 0. Person A is 2 generations from the shared ancestor; person B is 2 generations away. Along this path, you are 2 generations from the shared ancestor (grandparent), and the other person is 2 generations from that ancestor.
