[QUESTION]

Do dwellers recognize family members when breeding? I felt disgusted doing this buy i tried to put a Lucy and his son (both with high SPECIALS) were the only dwellers I have with very high SPECIALS in the vault cuz the father is exploring and they won’t breed (which is a good thing). But this sparked some curiosity… is the game that deep that they do recognize their members or is it just a charisma or happiness issue?
