who were separated at birth and adopted out to different families, not knowing that they had an identical sibling somewhere. In later years they discovered each other by chance or, these days, through genetic testing.

Some of the similarities between those identical siblings are probably just coincidence. But some are more convincing of genetically shared likes and dislikes.

Other examples being discovered recently are similarities between parent and child or between siblings who are not identical. These separated families, usually by divorce or adoptions, find some remarkable similarities in preferences and habits when they meet.
