B is the sister of A implies A is the sister of B?
As per the section title, if B is the sister of A does it follow that A is the sister of B? Siuenti (talk) 14:18, 27 July 2016 (UTC)


 * Yes, Siuenti, if B is the sister of A, it follows that A is sister of B, because both share a most recent common ancestor. Manudouz (talk) 11:52, 2 August 2016 (UTC)
